I have had RO water in my tank for the last month as I work through plumbing issues and get everything ready. I am just about there... this weekend I hope to be draining the tank, putting the rock and sand in, and then filling it with fresh salt water. The question is, should I give the tank a good vinegar wipe-down once it is empty? I assume the bacteria that has built up in the tank will not survive in salt (but could be way off base). If I don't clean it, I am guessing it would die and provide a bio-load for new salt water bacteria to start the tank cycling? Clean or don't clean?
