i have a 72 gallon bowfront aquarium, currently i have 2 aquaclear 110 power filters on it but was wondering if i should really use a canister filter and was wondering about uv sterilizers and if i should use one on my tank? i'm fairly new to the hobby and am hooked but i'm always looking to learn more about how to make my tank better. if anyone has some advice about what i should do with my setup i'd like to hear about it. thanks
