rio nano protein skimmer problem
so i just wasted 180 on some new lights for my nano tank..and the guy at my local fish store told me my adjustments on my rio nano were wrong..he told me my needle part was to low and not high enough..thats why i wasnt getting any skimmate or bubbles overflowing..
so i did that and still there are no bubbles overflowing or major gunk building up..
what should i do?
can i fix this so bubbles go overflow and build gunk
or buy a new skimmer
