Hello my name is Reuben, I'm from Chicago. I recently started a 55 gal Fowlr
tank. I don't have live rock in there right now but have 6 snails and 2 damsels. I want to use one of my old tank to turn it into a sump refugium set up. I just need some type of plan on the build. Example, space between each divider and equipment etc..... I'm currently using a ehiem canister. Thanks!
