Hello! I have a 90 gallon tank and I recently just finished my 29 gallon sump and I have run into a mess of issues.
First of which is micro bubbles and more micro bubbles.
I have an Eshopps single output overflow(I should have bought a dual) with flex tubing going down into my sump. When it does down into the left side it rests in a box with polyfill and small fine foam. Then I have a baffle, an area of sand and LR, and then three more baffles then my return pump which is vinyl tubing connected to a very large PVC spray bar.
I have added polyfill around the sump but it decreases my flowrate. I have moved things around on my overflow and I CANNOT get a reduction. My tank is cloudy due to the bubbles even.
The second issue which may be intertwined is my pump is uh, stronger than I anticipated. I bought a 1200gph pump. I assumed with my 48inch spray bar and 10 inches on each side going into my tank and 4ft head height I would have enough flow displacement. The flow was too strong. I added a ball valve between the vinyl tubing and PVC to decrease pressure but it seems to only help somewhat and I don't want to burn out the pump. I even turned off my protein skimmer because it was just making the problem even worse.
Attached are some photos. I can take more if needed.
Anyone got any solutions? I am going nuts over here.
