• Absorbs ammonia and avoids spikes
• Great for after a move or large clean
• Can be cut to custom fit your filter

This pad is designed to absorb toxic ammonia from the aquarium and as a preventative measure to avoid ammonia spikes. Especially useful after moving an aquarium, doing a large cleaning on a tank, or a power outage has occurred where the the balance of the tank has been disrupted. They can easily be be cut down to the size of your filter for a perfect fit.

Our ammonia pads come in a rigid 17.5 inch long and 9.8 inch wide pad. They come folded in half. Also serves as a great secondary polishing pad to remove unwanted waste and particles.

To use a sponge filter tank, simply wrap the ammonia pad around the sponge filter and fasten with string, zip tie, or a temporary rubber band.

We are often asked "How long do these last?" It depends on the amount of ammonia, so the only way to tell is by measuring ammonia. The more ammonia in the aquarium, the faster it will be exhausted.
