I've noticed that my display as developed micro bubbles that have become worse over time. The cause is my Reef Octopus 110 in the return chamber of the sump. For some reason, the Reef Octopus 110 seems to be leaking bubbles from the body into the return chamber of the sump and then into the display.
Any ideas as to when might be causing this problem?
