Anthony,
I just read through this entire thread and it has given me a lot to think about! I'm getting ready to build a replacement sump for my 75 gallon tank. I have a 29 gallon tank and will be building my own baffles. If you could take a quick look at my design, do you see any major design flaws or could you suggest any improvements?
A couple of comments:
1. The shelf going into the refugium was a suggestion I saw in this thread, to give a more laminar flow that will help rotate the cheato.
2. I can position the output from my skimmer to return to the drain section, allowing some of the water to go through the skimmer again, is this a good idea?
3. Is my bubble trap correct, under, over, under?
Thanks!
Brian
