Some canister and sump setups need a compact, easy-to-place biological filter chamber rather than loose media scattered through a media bag. The Dymax PRO-Cube is a self-contained 1.5L biological filter unit that drops into an existing filtration setup.
Why a Contained Bio Chamber Helps
Loose biological media works, but a dedicated chamber keeps it organized, easy to inspect, and simple to swap or clean without disturbing the rest of a canister or sump's media stack.
What the PRO-Cube Offers
- Self-contained 1.5L design that's easy to place within a canister or sump.
- Acrylic construction for durability in a wet filtration environment.
- Suits freshwater, planted, and reef setups alike as a general biological filtration addition.
How to Use It
- Fill with your preferred biological media — the PRO-Cube is a housing, not pre-loaded media.
- Position for good water flow through the chamber so beneficial bacteria get consistent access to oxygen and ammonia.
- Rinse periodically in tank water (not tap water) to avoid killing off the bacterial colony you're trying to grow.
