Thanks to the fine folks at Aquarium Life Support Systems and OASE Living Waters, I recently received one of OASE’s BioPlus Thermo 200 internal canister filters to review. I am really anxious to unpack this thing and get it going. I have used internal filters before, but never one this large. Recommended for aquariums up to 55g , the 200 is the largest of the three sizes in the BioPlus Thermo line.
Whether you’re familiar with OASE or are just now learning about them, they make solid aquarium products. If you’re interested in an external canister filter, see my review of their BioMaster Thermo 350.
