IceCap Phosphate Removal Filter Pad

The IceCap Phosphate Removal Filter Pad is a cut-to-fit pad built to trap debris while chemically reducing phosphate as water flows through it — phosphate being one of the main drivers of nuisance algae growth in both marine and freshwater systems. Best for: ponds, marine, and freshwater aquariums of any size Removes: phosphate and free-floating particulates Cut-to-fit: trim to match your filter, sump, or canister Chronic algae problems often trace back to phosphate rather than nitrate — if you're fighting persistent algae despite good nitrate control, phosphate is worth targeting directly with a pad like this one. Pairs well with: IceCap Ammonia Removal, Nitrate Removal, and Carbon Infused filter pads for layered filtration.
