I am really glad I tried to put the 20L in my tank before gluing in baffles. It is too long to get in the stand. I can't cut the stand. I do have the receipt and could exchange it for a 20H. I also have a 15g (4" shorter than 20H). This is what I'm thinking of doing. I do want a tiny refugium section because I like the chaeto to pull out nitrate. The plan with this one is to have the skimmer in the first section, then a bubble trap with the baffle higher on one side which will make the water flow into the fuge section first, then the return section.

Or I'm wondering if I could make the dividing baffle between the fuge and the return section out of egg crate. I just usually get algae on the walls of the fuge and wonder if it would hurt the pump. I did it sideways to keep the light out of the return section. I could do it the other direction if I can keep the light out of the return section.
