Hey everyone, so I have a 40g breeder. I am going to have it drilled and I think I will end up making a sump with a 29 or a 20L. My issue is that with most stands aside from getting one custom built, it looks like I wont be able to fit much more inside the stand and I am trying to work in another tank as a refugium. I have been been told that putting a refugium inside of the sump is the wrong way to do it. That the refugiums are made to have very little flow and that its too much to put it in the sump. Can anyone confirm or deny that? and can anyone give me an idea of how I can incorporate it all together or anything else? Thanks.
