I need some help operating my new/used asm g2 skimmer. I bought it used so it doens't have an instruction manual. I think these things are pretty much plug and play, but I put it in the sink, filled it up with tap water and plugged it in to see if it works ok. Well, the pump runs and everything but it wasn't making micro bubbles like a skimmer does. Is there something I'm doing wrong? Do these not work in tap water?
Thanks!
Thanks!
