I have a red sea 300 DC skimmer that I elevated with egg crate. Everyday I have to tilt the skimmer to release a few very large air bubbles. Is there any way to avoid this? Anyone else have this issue? TIA

Use a brick or bend some plexiglass with a heat gun and a board. If your not handy there are people on esty that will do it for you. Hell I am going to bend some plexiglass. Pay for the shipping and I will give it to you. What size do you need?
I get the same thing. Not a RC but a RO. Rock it side to side and big bubbles come out. I couldn't figure how the heck the bubble were getting there so I quit rocking it and they disappeared.

On the rare occasion I move my skimmer - maybe every few months - there are alway gas bubble under the base of it.
Why do they concern you?

This is normal for Skimmers with a bottom outlet.... Some of the microbubbles make it down and get trapped under the base eventually coalescing into large bubbles... It happens on my bubble Magus elite all the time.. you can ignore them if you want.

The water that leaves the skimmer exists through the bottom. When there's air trapped underneath the foam in the skimmer is real low until I release the air.

That makes sense. I'm having a heck of a time tuning this thing. Very I consistent. I'll pull out out and disassemble it to make sure I have all the pieces correct. Thank you

I don't understand how that would happen. The water height inside the skimmer is related to the column of rising bubbles from the skimmer pump and the air intake. Anything under the base of the skimmer should not have any effect unless it's actually causing the skimmer to float higher in the sump.
