I have had a few set up this way. I think they are not for everyone, and probably not for most of us here. I will say the best planted tank I ever had. Once’s it’s set up you don’t mess with it. I don’t do many water changes anyway on my well planted tanks. Anyway they can work, your first few may fail as you learn, last they aren’t for everyone. If you only have one tank you may not want do this on your tank if you have a fish room give it a try.
