An air pump or powerhead (a small submersible water pump) pulls water down through the gravel and back up the lift tubes, so the gravel traps debris and hosts the beneficial bacteria that break down fish waste. This is biological filtration: using living bacteria, rather than a cartridge, to clean the water. The air pump is sold separately.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular plates\u003c\/strong\u003e that join together to cover the 90 cm base as one filter bed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRuns on air or a powerhead\u003c\/strong\u003e, so you can start with an air pump and change later.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual airlift\u003c\/strong\u003e: an airlift is the upright tube where rising air bubbles carry filtered water back up into the tank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlates sit out of sight\u003c\/strong\u003e under the gravel, with even flow through the bed to cut down dead spots.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFits: 36 x 12 inch (90 cm) aquarium\u003c\/li\u003e\n\u003cli\u003ePlate area: about 86 x 30 cm\u003c\/li\u003e\n\u003cli\u003eIncluded: filter plates, lift tubes and airstones\u003c\/li\u003e\n\u003cli\u003eMaterial: aquarium-safe plastic\u003c\/li\u003e\n\u003cli\u003eDrive: air pump or powerhead, sold separately\u003c\/li\u003e\n\u003cli\u003eBioscape code: BIS592\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cp\u003eSuitable for 90 cm freshwater aquariums with 3 to 5 cm of gravel over the plates, including tropical fish, shrimp, goldfish and bettas.
