New to saltwater and after doin quite a bit of research I then realized I was given bad advice from a LFS, was told not to get a sump and get a basic aquarium with a fluval fx4 and don’t use live sand and other stuff like that, recently purchased a pro Lear 150 (120g with 30g sump) and all new stuff and in the process of mixing salt now and once ready will be transferring live stock from old 75g to new aquarium
