Skimmer keeps spontaneously overflowing.

[MarkoD]

My skimmer is already on a stand and at optimum water level of 8"

Air intake is also clean

Any epoxy used lately? That usually makes it go nuts.

Check the venturi on the pump. If it is starting to build up with salt it could make the skimmer a lot touchier. Might just need a good cleaning all around.

Alright.

Well, if you continue to have your skimmer overflowing issue, please think about raising it a little more and adjusting your skimmer....it can't hurt.

How long have you had the skimmer? When did it start this random overflowing? When's the last time you gave the whole thing a good vinegar bath including the venturi? Fwiw, I also think that considering the water depth is a reasonable step. manufacturer recommendations don't always turn out to be the best. Setting a tile or two under the skimmer might be an easy solution.

Fwiw, skimmer sizing has more to do with display volume than total system volume (within reason). This is because of the potential bioload, and generally the bioload is a direct reflection of the display tank size. Do you have a very light bioload?

When my Skimz SK181 (pretty much same skimmer) did this I found Ca built up in the venturi just below the airline fitting. This was a few months from new.
I now clean the venturi weekly and it hasn't puked in years.
