Best starter tank size

One word of advice - the BIGGER the better since there is so much to check that it can feel overwhelming at first. I'd say at least 55-75 gallons to start with to make it so much easier to learn as you go.

100% agree that the bigger that you can go, the more it gives you the room to let levels move around without having to constantly check. Normally around 40+ gallons is where people start with saltwater, unless you want to always check then you can go lower.

Thought I replied to this. Anyway, bigger is easier to work with.
