What kind of lights did you use?I love the 20 I used to run a 150 with a 100 gallon basement sump had to sell due to a move. I miss not being able to get what fish I wanted and have all the space. But I love how easy a water change is and I don’t run a skimmer in my 20’s. They to me seem a lot easier to care for. Also lighting is a lot easier and cheaper one light will cover the 20 no problem.
