I personally do not like that layout. I used an old 30 Gal tank for my sump/fuge and I put the fuge to one end and made it almost the entire height of the tank. In that design you are putting more water in the are where the skimmer sits. My skimmer can only handle ~7" of water depth. So, if I put my fuge after that I would have even less depth and subsiquent volume for my fuge. In my setup I have ~12 Gal of the tank allocated to refugium on one end of the tank. I run ~5-10% of my tank flow into there. I then have ~3 Gal allocated on the other end to trap bubbles coming from my tank. In the middle I have my true sump. Here I house my skimmer, heater, chiller inlet and outlet as well as the return pump. Since very little water runs through my fuge, I get little to no bubbles in the sump from that end. You really only have to worry about bubbles in areas of heavy water flow. Plus, if you incorporate a durso standpipe in your overflow then even fewer bubbles are produced. |
