i just got a used coralife superskimmer 65 and i am having a few issues, i also have an idea or two that i would like to run by everyone. i know since the skimmer hasn't been used for a while i am going to have a micro bubble issue it has lessened but still has some (started skimming yesterday afternoon). i also have an issue with bigger bubble that are being introduced to the tank, i know it wont hurt anything but i would like it to run smooth and silent. this skimmer is on a 29 gallon and the pump for the skimmer is so strong, i think i could get away with splitting the return line and taking out my powerheads. the back pressure might help with the big bubbles but i am unsure.
