There are several issues here.
- First, bacterial startups and water clarifiers will cause a skimmer to overflow. They have the same effect as adding soap to the water.
- Second, the skimmer is running too deep. The skimmer should be running in 6"-6.5" of water, no more.
- Third (and most importantly), the skimmer is way too big for your system. This skimmer is rated for 300 gallons and you are running it on a 92 gal tank. Once the chemicals that make the skimmer overflow are removed, the skimmer will not be able to collect anything. The skimmer body is too big for the amount of organics your tank can produce, even if the tank is heavily stocked. I would recommend going with a smaller skimmer.
