BIOHOME® ULTRA, ULTRA PLUS, and ULTIMATE, ULTIMATE MARINE are made with higher porosity (10% more) to support more oxygen exchange within the pellet, supporting better biological functions. These are generally larger pellets than BIOHOME® Standard & Plus. PLUS & ULTIMATE MARINE include trace elements to induce faster bacterial colonisation.
Canister, overhead, internal multi-chamber, trickle tower, and moving bed filters. DIY friendly: an air pump can drive a small conical “bottle” reactor at home. In larger sumps, use a stronger air pump or small powerhead. For static use, pair with mechanical media (e.g., filter wool) to prevent clogging.
No cleaning needed in moving beds. For longevity, leave no more than ~20% free space in the chamber. As a guide, ~100 g treats ~120 L of water; 1 kg is ~2.1 L of media.
(Biohome sintered-glass media is built to last; lifespan can be extended by topping up new media over the years.)
