alright i've done 7+ hrs of searching with mixed reviews on wither or not i should put a sump on my 75g display tank, i already know i want to as i dont run co2 yet and if i do it will be injected to the main tank anyways, only think im conflicted on is what size sump should i go with? i want to have a small area inside of the sump that will have a bit of sand and some java moss as a natural filter with light just curious what everybody thinks
