So the reason I asked is because my skimmer was going all wonky this week. Overflowing, dropping way down, I was constantly having to adjust the level. Sometimes it was hardlymaking bubbles but the water level was way up in the neck, just weird stuff so last night I yanked it out and took it apart.
First, my air intake hose was totally clogged with salt. Hardly any air could pass through so I cleaned that out and and now it sucks in WAY more air. Who knew...lol
Second, looks like a strawberry top hat snail had babies in my tank because there was a little teeny one stuck in my pump! Took the snail out of the impeller (I think thats what you call it) and cleaned out the body of the skimmer. Put it all back together and its ROCKIN! Works like new.
So ya, clean you skimmers from time to time people...lol
