Hello,
I’m sorry for budging in, but you shouldn’t put the skimmer on the floor of the sump.
If you want to know why, just simulate a power shortage and turn the main pump off.
After all the water comes down, start it…
The skimmer will start floating around and might tip over, and in addition will overflow.
There was a lot of thinking behind every single shelf and knob.
We flooded the lab a few times before adding the pedestal the skimmer is on.:smack:
So take it from my experience, leave the skimmer elevated.
By the way, why would you lower it to begin with?
Hope I helped,
