API Filtration 30 PPI
API FILTRATION 30 ppi (pores per inch) promotes crystal
clear water in your tank with a thick foam pad to filter small waste
particles. Use these foam pads in FILSTAR XP FILTERS.
Instructions:
Put a foam pad into the bottom filtration compartment, above a 20 ppi
foam pad. Every month wash the foam pad thoroughly in a basin of water
taken from the aquarium. Replace the foam pad every 3 months. Never
replace all filtration foam pads simultaneously so as to ensure optimum
biological equilibrium.
