Seapora Nitrate + Nitrite Pad 18″ x 10″
The Seapora Nitrate + Nitrite Pad is a dense chemical filter pad that neutralizes nitrate and toxic nitrite in freshwater aquariums. It reduces the possibility of nitrite poisoning and helps reduce fish stress caused by the presence of nitrite. Nitrates can cause kidney, liver, and eye problems in fish, as well as appetite suppression.
This media should be used as a preventative measure or treatment, not as a remedy for persistently high nitrate and nitrite concentrations. It is not a substitute for regularly scheduled aquarium maintenance. Use a test kit to check nitrate and nitrite levels regularly.
Seapora Filter Pads can be cut and shaped to fit any filtration system, including: Canister Filters, Hang-On Filters, and Undergravel Filters.

FAQ
Can this pad be used in a new aquarium setup?
Yes, it can be used as a preventative measure in a new aquarium to help manage nitrite and nitrate levels before establishing a stable biological filter.
How often should I replace the pad?
The pad should be replaced every 4 to 6 weeks or when the water test shows rising nitrate or nitrite levels, depending on tank conditions.
Does this pad remove all nitrite from the water?
It effectively reduces nitrite levels, but it does not eliminate all nitrite. Regular testing is recommended to monitor water quality.

I’ve used this pad in my 55-gallon tank for three months. Nitrite levels dropped from 0.8 ppm to below 0.1 ppm. My fish seem more active and less stressed. Easy to cut and fit into my canister filter. I still test water weekly, but it’s a helpful addition.

Works well for reducing nitrite spikes after water changes. I cut it to fit my hang-on filter. It didn’t eliminate nitrate, but kept levels below 20 ppm. Good for short-term use during maintenance.
Blake Hemmings –
After introducing new fish, nitrite spiked to 0.6 ppm. Used the pad and within a week it dropped to 0.05 ppm. My fish didn’t show any signs of stress. I plan to use it regularly during water changes.
