I just got my skimmer for my 55g tank it's a hob cylinder type with a sub pump at has air intake control. My question is what is the appropriate lvl to run then air intake (also controls the vol of water in skimmer)? I hand it at almost all the way open. Plus how long does it take to break in? No foam yet on any lvl setting. Then again tank is still cycling. Any help or instructions on how to run this thing would be greatly appreciated. Thank you.
