- Removes silicate and phosphate.
- Spherical for optimal hydrodynamics.
- Irreversible binding.
Overview:PhosGuard
rapidly removes phosphate and silicate from marine and freshwater
aquaria. Although PhosGuard is effective in both fresh and marine water,
it will operate better in sea water and the need for it is better
defined in sea water. It is not recommended for phosphate buffered
freshwater (PhosGuard would remove the buffer until saturated).
PhosGuard is highly porous and bead-shaped to promote easy water flow
through and around it, thereby increasing both its efficiency and
capacity.
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.
