product highlights

  • 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.

    Features:

  • Removes silicate and phosphate
  • Spherical for optimal hydrodynamics
  • Irreversible binding

    Intended For: Marine and freshwater aquaria

    Instructions:
    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® Phosguard™ is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from A MUST for all aquariums! If you're on well water or use another natural source, you've probably battled "brown algae" quite a bit. Actually, that annoying ugly stuff isn't algae at all but something called diatoms, a type of silicate buildup that's harmless, but irritating to look at. Pour a bit of Phosguard into a mesh baggy, pop it in your filter (canister or HOB), and done. A small amount goes a long way (I use roughly 1/3 cup for 55 gallons), and since I've started using it I've not had one outbreak of diatoms! Saltwater aquarists may have a different opinion on it (it's supposed to also absorb phosphates, which lead to purple algae in marine and reef tanks), but for freshwater it's some pretty amazing stuff! !!BE AWARE!! If you use a phosphate-based buffer in your tank (check the buffer label), Phosguard will basically cancel the buffer out and make it useless. Also, in the beginning you'll need to check and replace the Phosguard every 3-5 days until your phosphates and/or silicate levels are under control. The bottle claims it can be "recharged" and reused, but countless others (including Seachem's own page for Phosguard) say this is simply not true. Honestly, with as little as is used at a time I'd rather just replace it all than go through the tedium of trying to "recharge" the granules.
