I am thinkin of starting a 55 gallon with just fish.....do I need live rock, and if I do how much ? I am tryin to minimize cost.....I'll have a protein skimmer and live sand.
You will still need some other form of filtration such as a canister or a skimmer. But, you can get away with a bit more in a fish only system.without live rock you would need a filter or skimmer!
No,You need a filter and you should have a skimmer too,but if you do big enough water changes every week you could get away,but it would be better with one!without live rock you would need a filter or skimmer!
I would say 30-60 lbs, depending on how big the pieces are and how you want to aquascape. Tall narrow tanks like a typical 55 are harder to gt a nice structure in without sacrificing swim room.One part of the question had to do with how much live rock should be used in a 55g. What is the ratio of lb's to gallons?
