Product Information

Seachem PhosGuard removes phosphates and silicate from both marine and freshwater aquariums. It has a highly porous quality and spherical shape that allows for maximum water flow and the best results. It is not recommended for use in phosphate buffered freshwater aquariums.

PhosGuard will not leach any toxins, phosphates or silicates back into the water. Simply add the correct amount to a filter bag, or directly to the filter canister, drip tray, sump or box filter. Make sure to place it in an area of high flow, for the maximum water exposure.

  • Can be used in a variety of filters
  • Available in various sizes from 100ml to 20 litre tubs

    I have put the recommended amount into my filter and the phosphate levels are falling but its early days (2 days in) to say whether this is due to the Phosguard or whether due to the algae. I'm waiting/hoping for the algae growth to subside.

    Does what it's meant to do....pulls Phosphates and most importantly Silicates for me out of the tank.

    I've been fighting a battle of diatoms in my tank for months and it always seemed to be when I did a water change....my RO was at 0ppm and all my other tests came back as in the normal range for a marine tank.

    Tank has cleared up immensely within the first 4 days of using it so it's definitely pulling the the silicates out. Corals and anemones look healthier also.

    I would recommend this to anyone that maybe battling with diatoms.
