Hello Everybody. My tank is up and running. Becoming more stable every day however I have hit a snag! I Have a bad case of micro bubbles. I initially thought the skimmer was the issue, After isolating section by section I have discovered the source. It is coming from the sump inlet. I have a 3/4 id tube running for a durso into a filter sock that is made out of poly pad. I need ideas on how to trap the bubble anything will help.
