skimmer adjust question ???

[cracker]

I clean the skimmer cup weekly. There is usually a thick build up inside the neck. Do You think I run it too dry? Thanks for any OP's

I think that's typical. Mine is always like that too. That is why some companies make automatic neck cleaner attachments.

Nope, sounds about normal. Running it wet still gets you that nasty build up in the neck, just not as quickly.

Thank You Gents, I have tried different setting over the years, never saw any big change one way of the other.
