AquaEl Finish Foam Sponge 30 PPI for UltraMax and Maxikani Filters

This AquaEl finish foam cartridge is a replacement for UltraMax and Maxikani canister filters. The 30 PPI foam is a compromise between filtration speed and water clarity.

• Fits AquaEl UltraMax and Maxikani filters
• Finish sponge grade, 30 PPI
• Balances flow speed with water clarity

Rinse the foam in old tank water, never tap water, so you keep the beneficial bacteria on it.
