Safely and effectively removes phosphate (P04) from your aquarium.
There are different ways in which one can implement the phosphate removal media into their saltwater aquarium.
Aquarium phosphate removers keep phosphate levels low to prevent bloom of unwanted algae. If there's too much algae in your tank, it could lead to pollution and nutrition deficiency in corals and fishes. We have a lot of options for you to choose from: Aquamaxx, Blue Life, NYOS, Red Sea, Reef Interests, Rowa, Two Little Fishies, and our own GFO. Simply put a few grams of the phosphate remover of your choice in your filtration system or media reactor. These granules naturally absorb phosphates as water pass through the reactor. Removing phosphates is as easy as 1-2-3!
Treats: 1 large pouch treats up to 55 U.S. gallons of aquarium water Directions: Rinse pouch under tap water for several minutes to remove dust and activate the PHOS-ZORB. The activation process will temporarily generate some heat. Place pouch in path of water flow in the aquarium filter. Replace pouch every 2 months or when testing indicates the presence of phosphate or silicate.

Rocks and substrate Dead reef rock (also referred to as base rock), tufa rock, but also crushed coral substrate may contain serious amounts of phosphates. Some is bound very tight (pretty dissoluble minerals), some may be dissolved given the proper biochemical environment. If you want to know approximately how much soluble phosphate is contained in a specific rock or substrate, it is possible to test it in a bucket with heated and moved salt water for some days. Contents of 1 mg phosphate per kilogram of rock or crushed coral, and higher have been determined that way. A tank in which such rock is used will have high phosphate concentrations for a long time. If phosphate rich rock material is already in your system, there are two possible solutions: Take out the rocks, or increase the phosphate output of your system (see below).
The use of dead reef rock may be seen as one of the major sources of long term high phosphates in marine aquariums. If they are used they should be rinsed very well. Dead reef rock should also be scrubbed. Proper bleaching may be necessary to remove some of the more soluble phosphate containing agglomerations and minerals. Fresh and cured life rock, however, has a much lower phosphate content and should be preferred when setting up a new tank.
The industry provides a number of phosphate adsorbing media (e.g., PhosGuard, Phosphate Remover, Phosphate Sponge, RowaPhos, X-Phosphate,…), and the ones I tried worked as promised if applied as recommended by the companies. The adsorbing media consist of aluminium oxides and iron hydroxides specifically manufactured to have large surfaces. Usually, the media is applied in a fluidised bed reactor or simply in a very fine net at spot in the tank with medium current. On the surfaces of the granules phosphates are bound (adsorbed). When the surfaces are “full” and the concentration starts rising again, the media and the bound phosphates are taken out of the aquarium. Using this media is very helpful with any elevated phosphate level. The only danger with this technique is to drop the phosphate concentration below the level needed by corals for tissue regeneration. Therefore, it is important to monitor the phosphate level during the use of adsorbing media. It is also important to rinse the adsorbing media (preferably with RO water) at least every few days to remove the thin layer of bacteria that builds up around the grains and makes the media quickly ineffective by sealing the surfaces. Because organic molecules and some metals may potentially also be bound to phosphate adsorbing media, and thus decrease its efficiency, it can be recommended to use these media preferably after a few days of filtration with activated carbon.
Since I work in the environmental field (e.g. projects about ground water pollution), I’ve also tried iron hydroxides intended for large scale phosphate removal from drinking water in aquariums and found them to be just as effective as the aquarium products. However, I can only recommend them to people, knowing exactly how to apply the products for groundwater and drinking water treatment. Adsorbing media are a good solution for high phosphates in tanks with phosphate reservoirs from dead reef rock without having to remove the rock from the aquarium. They are also especially helpful in tanks with low to medium nitrates, but high phosphates, a situation that often occurs in tanks with anaerobic, de-nitrifying filters like DSBs and large fish. A definite minus is the high price these media command.
