was wondering if anyone is using one of these pumps. Mine is running my tank, uv sterilizer, algae scrubber and skimmer. I got the pump used and gave it a thorough cleaning before installing it. I now have a severe micro bubble problem. so bad in fact that it looks like its snowing in my tank. All my plumbing was both vacuum and pressure tested (its clear pvc hard) and no leaks were found. Am feeding pump from wet/dry sump and there are no bubbles near the feed. My skimmer is not creating bubbles nor is the algae scrubber. was thinking about changing the impeller but not sure if it will help or not. Any ideas????
