Here are a few more pics I didn’t get a chance to upload yesterday. I have a few questions:
Notice that the sand bed in the fuge of the sump is low in one corner. It’s about 6-7” in the back, then in the front it dips a bit especially in the right corner, this is because of the water which is redirected into the fuge from the pump. Will this cause a problem?
Also notice that there is not much collecting in the skimmer cup, and the bubbles don’t reach the top either. The skimmer has been running for about 3 weeks now, there isn’t much bioload though, is this the reason, or is the skimmer not operating properly?
