Looks to me like you need to build a box to sit the skimmer on so that it sits at the correct water height.
It also looks like once you do that you are not going to have much room (if any) to mess with the skimmer cup.
Otherwise, looks awesome!
Minor setback which I am sure you can workout fairly easy. Everything looks top notch to me!
Nice sump. I had a 220 dump about half of the water on my living room floor a few years ago. I woke up hearing these tiny drops went into the living room and was in 1 inch of water and was wetvacing at 3am not a good nights sleep.
btw, can Weld-On be used to seal a crack in Acrylic????
