I'm thinking about a canister for my 29g planted tank (partly from sand), but am unsure if I want to make the jump. I'm a stickler for keeping the filter clean, and I clean my HOB
every week when I change the water (and I also use water that is slightly muddy). While I'm not afraid of maintinence, how involved and messy is it? Also, what model of either do I want? I do like the Tetra Biobags as they are easy to clean. I may go with two smaller filters when I replace my (quickly) wearing Top Fin Power Filter 75 (again, sand). I want to keep one running when I have the other down for cleaning (and also to Bogardt if I need to start a hospital tank). Is a HOB
better for me or should I make the jump to a can? Which one(s) should I put in?
