Octo 202 classic leaking microbubbles

[tee2greenaz]

So I have an octo 202 classic in my sump. It’s been running for months, zero issues. The last couple days, it’s been leaking microbubbles into its section in the sump, which spills into the return pump, and into my main. I took it out (rather laborious because of the sump and stand design) and cleaned it fully today, thinking that would help it. I was wrong. It’s better, but still leaking bubbles. They seem to be coming from the intake area where the pump sucks in the water. Any thoughts on how to fix this?
