API Nitra-Zorb Size 30 1-Pack

API Nitra-Zorb is a filter pouch that removes nitrate from freshwater aquariums, dropping into most filters to help keep nitrate in check between water changes.

Key features

• Adsorbs nitrate that builds up as fish waste breaks down
• Fits inside most hang-on and canister filters
• Rechargeable in a salt solution, so one pouch lasts a while
• Size 30 pouch

A useful hand where nitrate creeps up, but it works best alongside regular water changes rather than instead of them; it is for freshwater, not marine. More filter media. Available for local pickup at our Lethbridge store.
