Maybe somebody can help out here. I have an Eheim 2260 running perfectly for about 2 years filtering my 225 gallon together with an FX5. I recently decided to move my FX5 to another tank and build a wet/dry filter out of Sterilite storage bins, some nylon pot scrubbers, and a used Mag pump. After connecting everything and working out the kinks, the 2260 started acting up. the output keeps spitting out tiny bubbles. I tried everything from cleaning the filter to turning off for 2 minutes ala FX5 to purge any trappped air inside. I checked my hose connections making sure there are no loose connections or anything. I'm running out of ideas.
