Well the past weeks ive been having trouble with my super skimmer 65. I have zero complaints before this. i am vodka dosing and mb7 dosing on my 29g tank and have been pulling a full cup of thick black nog out per week with it. recently it decided to stop taking air in. i cleaned the pump and cup with regular water and a tooth brush then put it back together and it worked fine but now i am back to the same thing.
the air line is clean i can blow air through the line (minimal effort) and get good bubbles in it or if i put my thumb over half of the pump inlet it forces the pump to draw that extra i blocked through the air line and it works fine.
anyone ever have a problem with your skimmer not drawing air and what did you come up with?
i have done some research and i think i will try a 1 part vinegar 1 part water solution later and let it run for a few hours. any other ideas will help! thanks!
