Hi, currently i've got a tank of (W)60cm x (L)45cm x (H)45cm and is using a 3 tier OHF (rectangular plastics). I'm also using the Fluval 304 canister.

Due to that OHF and the lighting set takes up half of the opening of the tank, are there any other OHF to use for my tank? I am thinking of changing it to a smaller one so that it is easier to maintain.
