Cut-to-size filter pads targeting a specific water quality issue mean you're not running generic mechanical filtration when you actually need to address ammonia, nitrate, or phosphate directly. IceCap's filter pad line covers mechanical-only and five different targeted chemistries.
Choosing the Right Pad
- White Poly Fiber Filter Pad - pure mechanical filtration, no chemical media, just resilient fiber that traps suspended particulate.
- Carbon Infused Filter Pad - combines mechanical particulate trapping with activated carbon embedded in the fiber, removing toxins, medications, and discoloration as it filters.
- Ammonia Removal Filter Pad - a cut-to-size 10in x 18in pad that traps free-floating debris while chemically reducing ammonia spikes as water passes through.
- Nitrate Removal Filter Pad - traps debris while chemically reducing nitrate (NO3) as water flows through.
- Phosphate Removal Filter Pad - traps debris while chemically reducing phosphate as water flows through.
- Phosphate+Nitrate Removal Filter Pad - combines both nutrient-reducing chemistries into a single cut-to-size pad, targeting the two nutrients most responsible for nuisance algae.
How to Use Them
- Cut to fit your specific filter compartment or hang-on-back chamber.
- Choose based on what's actually elevated in your water tests, rather than defaulting to a combo pad.
- Replace on a regular schedule, since chemical capacity exhausts before the pad looks visibly dirty.
