The bubble tower will be filled with live rock rubble, to help slow bubbles as well as just an area for water to enter.
For the sump, water will enter through the skimmer area at a slower rate (water will be fed through the recirculating skimmer, then expelled), then it will go through the cryptic/misc zone, then into the fuge. Then the bulk of the water will go through the bubble tower, and through the fuge, then through the bubble traps, to the return. Hope that makes sence. Thanks chrisqueenz. More to come later
