Phosphate Test Kits


While low levels of phosphates will not harm your fish, plants or invertebrates, high levels of phosphates will lead to algae blooms. Levels of 1.0 ppm are favorable for algae growth and at 2 to 3 ppm, algae growth is very likely to occur (see phosphate test kits). Ideal phosphate levels are 0.05 ppm, or less.

Phosphates come from a variety of sources: uneaten food, dead fish, decaying plants, tap water & fish feces. To reduce phosphates limiting the sources is key. Using RO water will help if your tap water has phosphates. Frequent water changes (easily done with a gravel vac)will reduce phosphates quickly, but it may not take care of the underlying cause. If phosphates persist, the aquarium phosphate removers on this page will help to reduce your phosphates. Some of these products will require the use of a media bag or a reactor.

The Kent Marine Phosphate Sponge is a ceramic medium which will absorb phosphates quickly (within hours) when placed directly in the water flow. The Kent Marine Phosphate Sponge works in fresh and saltwater aquariums or ponds to bring about 1.0 ppm of phosphate or silicates down to less than .05 ppm in a 120 gallon tank for every dry quart of medium. For silicate to be removed, phosphates must first be removed. Beads are cracked to expose more surface area and increase efficiency. This product will not release soluble aluminum compounds into your aquarium, causing negative reactions from your inverts, as competing products may. Will also absorb moisture for use as an air dryer for ozone, and can be renewed over and over in moisture removal service.

Seachem 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.
  • PhosGuard Article (Seachem Web Site)
  • Phosphate/silicate control
  • Use 250 ml for every 75 gallons. Leave product in place for 4 days, then test phosphate or silicate concentrations. 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.
  • Each 500 ml of PhosGuard treats over 150 gallons (i.e. will remove up to 30 mg/L phosphate in 150 gallons of water, depending on the initial phosphate/silicate concentrations and the current biological load.
