    Noob ATO question

    Hello everyone, first time poster. So I’m about a week in cycling my tank and I’m looking to add an ATO. I like the idea of using a float valve.

    Build Thread Will's 100 Gallon Reef Tank

    Posting my 100 gallon mixed reef tank here. I have been at it for years but recently figured out that good lighting means I can grow more corals. Now its time to move the tank to replace the flooring in the house. Maybe I can get some tips on how to improve upon the tank. I have some great ideas.
