Update: now have a pair of clowns, 1 cleaner shrimp, 1 porcelain crab, 2 hermits and 5 turbos in. Feeding mix of flake, pellet and mysis. Parameters generally look OK but struggling to get my alkalinity right. Ph consistently at 8.0 but can't get alk above 7.0. Don't know whether to dose to get it higher or not. Any suggestions anyone?
