I had a 40 gallon innovative marine fusion. I loved it, I had a lot of nice corals. Inexpensive since small colonies looked big in a small tank. Maintenance was a breeze, every week a 5 gallon water change. I also had an auto top off running for the system… honestly feel small tanks are easier to take care of and less stress. Not sure why everyone says “bigger tank the better.” I had a 150 gallon tank with no corals and 50 gallon bi-weekly water changes was annoyingAnd here I am with my 25g
Nanos are great for low cost and easy maintenance!
