New marine tank, please help!!!
I've already had a marine tank before (a RSM 130d) although it's a nice tank I did have a few problems, the tank temperature was fluctuating quite badly and Cyanobacteria was a real problem. Is there any advice to give to stabilise tank temperature without buying a cooler and how to rid myself of cyanobacteria? I am going to upgrade the protein skimmer because the standard one isn't great so any advice about which skimmer to get is also appreciated.
