I was just thinking about a setup for a sump with 2 chambers. First will have the skimmer and the second will be the return pump and maybe in the future a media reactor with the input and output both in the same chamber. I'm not doing a refugium area because I heard that if it's too small (this would be in a 30x18 sump) it's not that useful. My question is how do I get the detritus and other junk to settle in one of the chambers so I can find all of it easily and vacuum it out. Is there a certain way to do the baffles? The other question is how do I get any dirt that gets into the bubble trap out since the 3 baffles will be only 1 inch apart. I don't think my vacuum wil fit in there. Thanks
