Our take on the Aqua Natural Pisces Live Ceramic Rings Filter Media

Aqua Natural Pisces Live Ceramic Rings are porous ceramic biological filter media for freshwater and saltwater aquariums. The rings give nitrifying bacteria surface area to colonize, converting ammonia and nitrite into nitrate. One 16 oz can is rated for tanks up to 50 gallons and fits sumps, canister filters, hang-on-back filters, media bags and reactors. At $10.63 at Poseidon's Realm as of November 4, 2026, it sits at the low end of its recent range across four stores.

Questions and answers

Is this enough media for a 50-gallon tank?
Yes. One 16 oz can is rated for tanks up to 50 gallons. Larger or heavily stocked tanks may need a second can.
Can I use it in saltwater?
Yes. It is rated for both freshwater and saltwater and works in sumps and reactors.
How do I clean ceramic rings?
Rinse them in removed tank water during maintenance. Tap water can kill the bacteria the rings are meant to hold.
Does it need to be replaced?
No. Ceramic rings don't dissolve or break down, so they last indefinitely with occasional rinsing.
Is it better than a sponge filter?
They serve different roles. Rings add biological surface area inside an existing filter; a sponge filter provides both mechanical and biological filtration.
When is the price lowest?
At $10.63 at Poseidon's Realm as of November 4, 2026, it is near the bottom of its recent range. Check the price history before buying.
