Looking to start a 33 gallo long. Tank will be 48x12x12. Stocking will be african peacocks and yellow labs. I usually use hob filters such as aquarist or whisper and call it a day, but I feel with such a shallow tank the filters will make a sandstorm and suck sand into the filter. Am I going to have to get two small HOB FILTERS? how do canister filters compare as far as how much electric they use to the hang on backs?
