Aquarium Advice Apprentice
I have a pro clear 150 skimmer and had it running I can't seem to get it tuned right. Do the bubbles need to go up into the cup or the bottom. I'm still cycling "fishless" not sure if this will affect it. I know it won't be skimming anything but I'm trying to get it down now while I don't have fish in it. Any help or links would be greatly appreciated.
