I was surprised you didn’t mention lanthanum at all for phosphate removal. Do you disagree or have any further comments? Acid oxides are also known as acid anhydrides.

Basic oxides gives a base in water. Scrubbers cannot “over scrub”, because they use the same mechanism for filtering (photosynthesis) that corals use to grow. Summary I test with Hanna Instruments ULR Phosphorous test to get a better picture of my total available phosphorous. Even at three times the dose, soft-bodied corals such as Sarcophyton remain unaffected. Main Difference – Aluminum Oxide vs Silicon Carbide. I use RowaPhos and Chemipure Elite in a dual chamber reactor (BRS), for nearly a year now with excellent results and long life, with a low tumble. Phosphate (PO4) is directly related to algae outbreaks and coral health as lower phosphates (<0.03 ppm) usually mean less algae outbreaks and healthier corals. We get it in a form similar to BRS gfo. © 2021, Seachem Laboratories, Inc. All Rights Reserved | MAP Pricing Policy | Returns Policy | International Terms of Sale | Domestic No-Export Policy | Privacy Policy Since when is GFO cheap? Metals such as manganese, cobalt, nickel, and zinc are known to bind to iron oxide hydroxide in simulated seawater solutions. Internet research highlighted that a reactor was the only effective method of using RowaPhos; otherwise save your money! RowPhos or “rowa” for short is widely used in Europe. just wondering your take on it. Aluminum fluoride oxide (AlFO) Aluminium fluoride oxide. Acidic oxides gives an acid when combined with water. Aluminum oxide is also known as alumina. Just placing the bag of RowaPhos in the reactor is very inefficient as most of the water flowing through the media bypasses the bag and little or no phosphates are absorbed. It’s inert and safe to leave in your filter. It is an inorganic compound. Phosphates are a parameter I monitor in my tanks and phosphate absorbing medias are the easiest way I’ve found to keep my phosphates in check. Overview and Key Difference 2. For best results, PhosBond™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. Designed by My Amanda Design. It is also known as alumina, and exists naturally as corundum or bauxite. Oxides are one step. Tabular aluminum oxide is recrystallised or sintered α-alumina, so called because its morphology consists of large, 50-500 μm, flat tablet-shaped crystals of corundum. Differences between Alpha and Gamma Aluminum Oxide Nanoparticles. Your email address will not be published. They can also remove to much iron. If you can’t get your hands on GFO, then PhosGuard is a good alternative. Regardless of if you are sanding wood or metal, aluminum oxide is the most frequently used grain in the industry because it does a pristine job on a number of materials including bare wood, painted surfaces, and metal. A: Not at all! Maintaining low phosphate levels will help prevent algae outbreaks and control growth. A: The main difference between these medias is capacity. PhosBond™ has a higher capacity than PhosGuard at 1.19 mg/g of PO 4 bound, and combines the benefits of PhosGuard and a pure GFO (strength, high capacity, and rapid phosphate absorption) while still being very economical. Silicon carbide is a semi-conductor material. The opposite can be said of pellets, gfo, nitrate reactors, etc; they don’t care what the status of the corals’ photosynthesis needs are. CONTENTS. For the full report on this study, click here. You can also call 888‑732‑0003 (Monday- Friday 9:00 AM - 5:00 PM EST) if you would like to speak directly with a technical support representative. I wanted your take on Red Sea No3 Po4X to reduce Phosphates as well as Nitrates. Its just rust and is very expensive at brs i think. It rapidly removes phosphates and silicates from saltwater and freshwater, combining the best of both types of phosphate removers. In reality, the native oxide is not a simple crystalline mineral. Structural difference: in terms of structure, the alpha-alumina is trigonally structured (R-3c) with an ABAB arrangement of planes of oxygen along the c-way. John..kalk doesn’t bind a lot of phosphate especially when compared with these media. Place the product in a high flow rate area and test your phosphate levels, changing as needed. I’m really happy with the results I’ve been getting and run PhosGuard or PhosBan in my reactor only as a backup. Phosguard is a different product altogether called aluminum oxide, but it also can be used in a similar fashion as a filtration and/or reactor media. This media has a higher capacity than any other GFO on the market. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Additionally, aluminum oxide is not easily absorbed into the cell to cause negative reactions. Also, adjusting the flow so that the granules simmer like garden peas in a hot saucepan on the hob will keep the media absorbing without escaping and prevents it from clogging up into a solid lump. My Nitrates are undetectable and it took a while buy my phosphates have dropped to 0. If you have low levels of phosphate the PhosBond™ will absorb the silicate in your system. The reason I stopped using it and went with Phosguard is because Rowa makes a huge mess and has a tendency to clump. AlFO. Its high porosity and surface area give it a large binding capacity, while its physical strength and integrity assures that it will not break down from mechanical stress. Can’t beat it. Our aquavitro® phosfiltrum™ is a super-high capacity GFO (1.71 mg/g of PO4 bound) that produces very little dust. It is very rare on earth crust but is common in space as stardust. hi Mark. My phosphates without these two products has still kept my phosphates extremely low to 0. A typical oxide polish scenario (for me) is to cut the stone to a worn 1,200 grit lap and then polish with either cerium or aluminum oxide. I’ve been using NO3/Po4-X by Red Sea and have gotten excellent results. Thks. I go months without changing GFO and my phos reads 0 or little to none. Inorganic oxides are binary compounds of oxygen with an element. details about seachem phosbond (250, 500, 1000) gm gfo aluminum oxide granular ferric oxide free shipping - authorized dealer = full warranty 225g display, mixed reef. Therefore, I don’t recommend the higher capacity GFO products. Use 60 mL (¼ cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. Aluminum oxide is very similar to polyurethane finish, though it is more durable and lasts much longer. It has a high melting temperature above 2050°C and is chemically stable. It can easily clump up in a media reactor and must be thoroughly rinsed before being placed in your systems. What do you think about chemi-pure and purigen? Office hours: Monday- Friday 9:00 AM - 5:00 PM EST. \[Al_2O_3 + 6HCl \rightarrow 2AlCl_3 + 3H_2O\] This reaction and others display the amphoteric nature of aluminum oxide. Can't find what you're looking for? i wonder why you never mentioned dr. tim’s pearls, i have been using them now for a while, just ordered more actually, and i have had excellent results with both phosphates and nitrates at zero or close to it. Leave product in place for 4 days, then test phosphate or silicate concentrations with either MultiTest™ Phosphate or MultiTest™Silicate. The results of these experiments show that under reef conditions (pH near 8) there is no detectable soluble aluminum released from alumina. It looks like giant lava/grill rocks! I use RowaPhos in a small reactor in my sump, It does work well. Alumina is a white powder-like table salt. Ferric oxide coated aluminum oxide phosphate adsorber, High porosity and surface area give it a large binding capacity, 1000 Seachem Drive, Madison, GA 30650, USA. PhosNet™ has the highest capacity of the Seachem phosphate absorbers at 1.41 mg/g of PO4 bound, and is a pure GFO media. PhosGuard (Alumina Oxide) 0.87 mg/g: PhosBond (GFO and Alumina Oxide hybrid) 1.19 mg/g: PhosNet (GFO) 1.41 mg/g Mark, or anyone else, have you tried the Brightwell Aquatics Xport-PO4? I am of course partial to natural P removal via algae, especially when the photosynthesis of the algae is increased by a scrubber. Copyright Mr. Saltwater Tank 2015. SantaMonica: The main problrm with algae scrubbers, or refugiums, is that whilst they can not over scrub, they can very easily under scrub. Hobbyists will often get up in arms about PhosGuard as it is an aluminum based product and is rumored to leach aluminum into your tank water. It’s small, get everywhere and expensive. Sometimes it is difficult to choose the right quality flap wheels. A: We do not recommend it, as the tumbling action of a media reactor can cause this media to produce dust. Usage of content from this website is only intended for authorized distributors and sellers, and by individuals for private use. Reaction with acids: Aluminum oxide contains oxide ions, and thus reacts with acids in the same way sodium or magnesium oxides do. Here’s a hint…if the pH gets to 5.3 in your reef tank, your coral and your fish, will be long since dead. 4,5 It has also been claimed that the binding of copper and zinc by natural iron oxide hydroxide sediments exerts a powerful control on the concentration of copper and zinc in polluted rivers and estuaries. So, through a series of controlled experiments in both freshwater and saltwater, we intended to address both the question of aluminum solubility and aluminum toxicity. Aluminum Oxide. To evaluate zirconium oxide wear resistance in a ceramic-ceramic coupling, a “ring on disk test” was performed. GFH vs. GFO. We have no interest in artificially puffing up our numbers, so the capacity we have listed is the amount of phosphate that the media can completely remove (without releasing back into the water) in a pH of 8.4. Ask us a new question. I say “usually” because every tank is different. If you follow manufactures guide lines with gfo, then it is very difficult to suck your tank 4 below 0.005 po4 of natural sea water. I personally don’t use PhosGuard in my tank as Granulated Ferric Oxide (GFO) absorbs much more phosphate. The 4 day replacement period is a function of how quickly the media works, not a function of how high a capacity the media has. PhosBond™ is a revolutionary new product that combines the phosphate removing capabilities of both aluminum oxide and granular ferric oxide into a singular material forming a synergistic effect. for automotive sheet, rely on cleaning and pretreatment processes to remove this largely uncontrolled oxide layer. PhosGuard has the lowest capacity at 0.82 mg/g of PO 4 bound, but is the most economical of the four medias. Despite how damage resistant aluminum oxide is, it is far from perfect. Thks. Also lanthanum is great. SeaChem released a research paper on the solubility of aluminum oxide and concluded that “The results of these experiments show that under reef conditions (pH near 8) there is no detectable soluble aluminum released from alumina. Phosguard is NOT GFO. I’m running a 220 gal 40 gal sump mixed reef tank about 250 lbs live rock and my clean up grew numbers are lower than recommended. This site uses Akismet to reduce spam. Although the two terms aluminium and alumina sound similar, they are different. Information is not commonly available on this compound; it is unstable, has complex high-temperature spectra, and is difficult to detect and identify. A: The main difference between these medias is capacity. These pictures show the differences between blasting an aluminum part (middle of top picture) with either a Glass Bead – 100/170 Medium-Fine and Aluminum Oxide Grit – 220 Mesh.. Comparing Seachem Phosphate Removers Product PO4 bound PhosGuard (Alumina Oxide) 0.87 mg/g PhosBond (GFO and Alumina Oxide hybrid) 1.19 mg/g PhosNet (GFO) 1.41 mg/g See More Ace Story Aquatic December 31, 2020 at 12:35 AM PhosBond™ is a revolutionary new product that combines the phosphate removing capabilities of both aluminum oxide and granular ferric oxide into a singular … Joel…Chemi-Pure is ok but for me it doesn’t last as long as GFO. Aluminum Oxide vs Zirconia Flap Disc. Also, you can over dose kalk quite easily especially if your tank isn’ deficient in calcium or alkalinity. Because of the higher cost due to import duties, the inability for me to buy it in bulk, and since it doesn’t work well in a reactor, I don’t use RowaPhos in my tanks. Continuous use of small quantities is better than intermittent use of larger quantities. Additionally, aluminum oxide is exceedingly durable. Examples of Acid oxides are Sulfurous acid, Carbonic acid and Sulfuric acid. Both these compounds occur in the white crystalline solid-state at standard temperature and pressure. PhosGuard is available in bulk which is great for large tank guys like myself. PhosGuard has the lowest capacity at 0.82 mg/g of PO4 bound, but is the most economical of the four medias. On all my tanks and on my client builds, I always have at least one method of phosphate control running at all time with the most common method being phosphate removing media placed in a reactor. Use of a filter bag such as The Bag is recommended. Aluminum oxide reacts with hot dilute hydrochloric acid to give aluminum chloride solution. The results (medium print deepness: 16 mm 3 /h for zirconium oxide vs 0.0033 mm 3 /h for alumina oxide) make the zirconium oxide unsuitable for the use in clinical application as ceramic-ceramic coupling surface. What is Zirconia 3. Mark You can use Rowa just like any other gfo. As long as you position the disc shaped sponge provided at the top of the reactor, there is no leakage of granules back into the sump. Alumina is a very strong ceramic, far superior to calcium phosphates, and has a high strength even at porosities of over 90%, as shown by a series of papers published between 2005 and 2015 on foamed alumina tissue scaffolds published by … The purpose of granular ferric oxide is to inhibit algae growth by removing phosphates from the aquarium. That’s it. The Aluminum Oxide Grit blasted part also has a uniform finish but is more etched and ‘darker’. I have had a great result with fauna marine ultraphos- you can get it in aluminium or gfo version. In an environment with an excessively high phosphate reading, PhosBond™ will exhaust rapidly (4 – 5 days). Mark, I use Rowa concurrently but I do not know what is the “GFO” do you have a picture. Write-Up Wednesday: 3 Phosphate Removing Medias and My Experiences With Each. Continue to test weekly for phosphate until you see it begin to rise again. If it takes a phosphate absorber several months to reach its full capacity when the tank has high phosphates, it means that the media is exceptionally slow at absorbing phosphate. It is naturally occurring as either corundum or bauxite. Hi Mark, its only since they’ve depleted some that my levels started to rise a small bit. Use 60 mL (1/4 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. That bag is placed in your tank or sump. Done. Not sure if I am missing out on something, but I usually use BRS GFO and it’s far from cheap, imo…lol. Hi Mark, You will then know that it is time to change the PhosBond™. The Glass Bead blasted part has much more a peened, smooth, uniform finish. A: It is actually quite easy to change the apparent capacity of a GFO during testing. Zirconia, including yttrium stabilized zirconia (YSZ), is also widely used in machinery industries. Can I make it clear ROwa & GFO is it same materials with different name/brand. What brand and size reactor would you suggest for a 55 gallon tank ? I’ve used lots of phosphate removing medias and these are my experience with the three most common ones: RowaPhos, PhosGuard and Granulated Ferric Oxide (GFO). Aluminum oxide. Prior to using it in a reactor I did just place it in a bag in the sump and it wasn’t effective and clumped up into a solid mass. In laboratory batch and column experiments, the synthetic challenge water was used to evaluate the effectiveness for five adsorbents. Also, although I personally have no use for biopellets, I think it would be worth noting that a system needs to have some phosphate present for biopellets to be effective at controlling nitrates. If a system is using both biopellets and GFO at the same time it seems to me the user is working at cross purposes. The evidence to support this claim was largely anecdotal. Granulated Ferric Oxide (GFO) GFO is an granular iron based product and is widely used for phosphate control due to it’s low price, widespread availability and high absorption capabilities. iodine, and potassium. One of the experts from our technical support staff will be happy to promptly respond. Alumina is a compound, which includes aluminium chemical element. GFO doesn’t come without drawbacks though. To bring things to manageable levels (tangs don’t like it as it effects they gills and can kill them ). Over treating is not recommended. Likewise, there are several other important differences between aluminium and alumina that we are going to discuss in this article. Since I can easily buy it in bulk at an affordable price and I’m ok with the added maintenance of GFO, I use regular grade GFO on my tanks. Some of the phosphate-removing products are marketed under the chemical name Granulated Ferric Hydroxide…which is essentially the same thing as GFO. John. It is an oxide of aluminum. PhosBond™ has a higher capacity than PhosGuard at 1.19 mg/g of PO4 bound, and combines the benefits of PhosGuard and a pure GFO (strength, high capacity, and rapid phosphate absorption) while still being very economical.
