AQUA ONE NITRITE/NITRATE PAD – SELF CUT
The Aqua One Nitrite/Nitrate Pad is a tightly woven chemical filter pad designed to absorb harmful nitrogen compounds in aquarium and pond water, including nitrite (NO2) and nitrate (NO3).
Nitrate buildup can lead to kidney, liver, and eye issues in fish, suppress their appetite, and impair gill function, reducing their ability to absorb oxygen from water. Using this pad helps reduce the frequency of water changes and improves water quality.
Compatible with a wide range of filtration systems including hang-on filters, canister filters, trickle/mini reef systems, top filters, internal filters, pond filters, and other aquarium or pond setups.

I’ve used this pad in my 50-gallon tank for three months. Water quality has improved noticeably. The self-cut feature made installation easy. I replaced it after 5 weeks as recommended and saw a drop in nitrate levels. My fish seem more active and their appetite is better.

Works well with my canister filter. I cut it to fit perfectly. After four weeks, I noticed less frequent water changes. The pad is durable and the nitrate levels dropped significantly.

Great product for a small pond setup. It fits well and absorbs nitrite and nitrate effectively. I’ve used it twice now and the water clarity has improved. Easy to cut and install.
