Macropore Resin Micro Filter Media

Macro-pore is a synthetic absorbent polymer that removes impurities from water and polishes it to a crystal clear clarity. Macro-pore will remove tannin caused by driftwood, leaving the aquarium water crystal clear.

It can be used in salt or freshwater aquariums. Use until it darkens. It can be recharged with Chlorine to re-whiten. Replace every three or four recharges.

1 litre of Macro-pore will treat 4,800 liters
