The Blue Circle Nitrate Pad is a tightly woven chemical filter pad which helps to absorb Nitrate (NO3). Nitrate can cause kidney, liver and eye problems for fish, as well as suppress their appetite and prevent their gills from absorbing oxygen from the water. The use of a Nitratepad can help reduce the frequency of water changes. It is essential you replace the Nitrate/Nitrite pad after 4-6 weeks. The microscopic pores in the pad can fill up and release all the waste previously collected, back into your aquarium
