Seachem® Phosguard™ Removes Silicate & Phosphate 250 Ml
We Offer FREE Shipping across U.S
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 ?ow through and around it, thereby increasing both its efficiency and capacity. CAUTION: When wetting the product for the first time, it should be made wet with twice its volume of freshwater by adding the product to the water. Avoid adding water to the product. Avoid using marine water for the initial wetting. Adding marine water to the dry product may generate sufficient heat to boil the water. Freshwater generates much less heat and adding the product to the water allows the heat to dissipate safely.
