Pic of my skimmer waste container, IO 200 gallon pail.
I have a toilet plunger inside that has some styrofoam attached to it to allow auto-shut-off. This worked well, but if the skimmer ever filled the pail the shut-off would cause soo much back-pressure on the skimmer that it would lift up and move everything in my frag section of my sump.
The solution was to add a 10 inch long pvc pipe to the input of the pail. Once the pail was filled 65% of the way the pipe would be submerged and cause the skimmer to slow down considerably, but not stop. Then the fuler it gets the slower the skimmer goes, so it hasn;t been a problem now for over 2 years.
