Hi guys, I'm helping someone set up a 55 gallon tank for plants, and I told him that a wet/dry was overkill for that small a tank and to buy a good canister filter. First of all, am I wrong in this presumption? Second, can anyone recommend a good canister filter and a place to find it fairly inexpensively? Please respond via private email if this is a little too off-topic. -Roni
