Description:Seachem PhosGuard ™Removes silicate and phosphateSpherical for optimal hydrodynamicsIrreversible bindingDescriptionPhosphates are present in every aquarium and if they aren't properly maintained the levels will continue to go higher and higher causing algae growth . Phosphates arent directly harmful to your fish but the alge blooms which will occur can deplete oxygen which would then effect your fish . Phosphates naturally occur as wastes are broken down within the aquarium but can also be added as anything from food , chemicals to buffer water and the actual water could contain phosphate.Seachem PhosGuard ™ rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater.Seachem PhosGuard™ is highly porous for high capacity and bead-shaped for optimum water flow.PhosGuard is round . Its shape allows for maximum water flow through the media. Granular phosphate removers can become compacted, dramatically limiting their capacity to remove phosphate. If the media can’t come into contact with the water, it can’t remove phosphate from it.In recent years, there has been speculation that aluminum oxide based phosphate removers like Seachem PhosGuard ™ release aluminum into the water and subsequently damage corals. The evidence to support this claim was largely anecdotal.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. The results of these experiments show that under reef conditions (pH near 8) there is no detectable soluble aluminum released from alumina. Under conditions of low pH and high dosage levels, soluble aluminum can be released from alumina; at three times the label dosage rate, we detected 0.2 mg/L aluminum at a pH of 5.3.
