The only way to prevent it is to eliminate splashing and misting from the tank. Seal spashdown areas, eliminate bubbles as best you can, and keep that damp sponge handy.
Yeah, I guess that’s the problem I have on one of my tanks where I’m using an Aqua Clear filter. The splashing and micro bubbles are escaping the cover. I’ll have to rethink my filtration method for this tank (24x18). Have been thinking of building a drop-in AIO filtration, like those used in IM AIO tanks.
