Description
| Comparing Seachem Phosphate Removers | |
|---|---|
| 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 |
PhosGuard™ rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater. PhosGuard™ is highly porous for high capacity and bead-shaped for optimum water flow.
Aluminum Oxide, Soluble Aluminum, and Coral Toxicity
In recent years, there has been speculation that aluminum oxide based phosphate removers like 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.
Additionally, aluminum oxide is not easily absorbed into the cell to cause negative reactions. Even at three times the dose of PhosGuard™, soft-bodied corals such as Sarcophyton remain unaffected.

Directions
May generate heat on initial contact with water. Pre-wet by adding to a double volume of freshwater, followed by a rinse. For best results, PhosGuard™ 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. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is recommended. Use 85 mL (1/3 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater.
Leave product in place for 4 days, then test phosphate or silicate concentrations with either MultiTest™: Phosphate or MultiTest™: Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mg/L, then replace the PhosGuard™, otherwise leave in place until levels begin to climb again. As long as concentrations remain under control, the product is not exhausted. Over treating is not recommended. PhosGuard™ is not an exchange resin and does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted. Continuous use of small quantities is better than intermittent use of larger quantities.
Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.
For over 40 years, Seachem has been a company rooted in sound science. Our experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized that the available solutions to aquarists' problems were wanting. This resulted in Seachem’s very first product: Cupraplex™ (today known as Cupramine™). Over thirty years later, Seachem is still approaching old problems in a new way.
Seachem has been in business over 40 years and is now sold
in over 60 countries worldwide.
Innovation means approaching old problems in a new way. Seachem doesn’t simply repackage old ideas, nor do we package new ideas that require the suspension of fundamental physical or chemical principles. We offer truly innovative solutions that work better than competing products and save money through increased efficiency and concentration. Seachem products have been and continue to be based on sound science. They now cover the full spectrum of aquarium requirements in freshwater, seawater, reefs, and ponds as well as herpetological and avian husbandry. They include buffers, conditioners, filtration media, medications, and test kits. The JurassiPet® line includes foods, nutritive supplements, and products for enclosure maintenance and parasite control. Most of Seachem’s products are totally unique and specific to Seachem. With our premium line, aquavitro®, our goal is to have a line that is an outlet for rapid response to the advent of new technologies and information as they arise, something we couldn’t do with the very well established Seachem line. We’ve distilled the essential components of reef keeping and plant keeping into a no compromises, rigorously optimized product line, and added conditioners and filtration that outperform the already high standards we've set with the Seachem line. We’re committed to maintaining that optimization.
