Aquarium Rocks

Ammonia is the #1 killer of backyard and aquarium fish. Keep ammonia in check with natural Zeolite, Poseidon Filter Rocks.

Why Choose Poseidon Filter Rocks

• Poseidon Pond Rocks enhance the ability of a ponds biological filtering capacity using 100% natural Zeolite to remove ammonia and other harmful toxic substances that build up from fish and algae.
• Strengthen the biological environment and help keep your fish healthy.

How it Works

• At the start of each season, in either mature or new ponds, there is a lack of nitrifying bacteria which controls ammonia and nitrite levels.
• Fish can die of ammonia poisoning during the development of the biological filter during the first few weeks.
• Poseidon Pond Rocks attract and hold ammonia, making an ideal surface for the growth of nitrifying bacteria. The healthy bacteria grow faster to produce a larger and more active filtering system to control ammonia levels in backyard ponds.
