I went from a 180 gallon system down to a 29 then to a 40 and now back to the 29 (seam let go on the 40 last week) Big pain trying to keep things stable with a smaller tank but I did find a solution. I added a 20 gallon sump and plumbed in a 7 gallon cube now with the extra volume things are easier to manage .last night my wife who has no use for the hobby says to me you should have just kept the big tank it looked nicer than all the small ones.
I should have never sold the larger tank
