There is little to no information out there on troubleshooting. I've got it to where the water level in the sump is stabilized, now just need to add some more to get it where it needs to be.
The whole thing is straight frightening as I did discover my one mistake. I didn't check for plumb on the sides. Tilts a small amount to the front. This is ensuring the water level is at the overhang and was freaking me out. I got over it and gave it more water.
NOW is simply getting everything tuned in. I dislike the diaphragm they use to adjust the flow into the sump. Would have been much easier doing a valve after the return pump. Even though the return feeds the skimmer as well, could have restricted after the T off. Would only have meant more water for the skimmer.
So, now I'm stuck trying to adjust the diaphragm so that it's silent without cutting the flow to the sump itself, then starving the return and causing the overwhelmed bubbles in the display.
I have yet to get the skimmer going. It runs. Last night it produced bubbles for me. Today it only gives water. Probably have to take it apart too.
All in all, my frustration aside this has gone over pretty well. It would have been much more streamlined of a process with clearer instructions and simply more information about possible issues, even if it was for me to relax and keep adding water.
Currently salinity is sitting at 1.028. More water to go in will bring that down. The two cobalt heaters are doing well. They take time to get to temp but it's smooth sailing once there. Really glad BRS videos existed for comparison. Was an even bigger help in making the decision.
So, once to temp, just waiting on the powder brown and to start transporting the other tank.
