Thank you SOOO much!!! It's the bubble curtain! It's too long! I had a bubble wall, but it only spit bubbles in one spot, so I replaced with a curtain. I could hear the bubbles going into the free, but didn't realize it would hurt anything. I'm replacing today with a smaller one. Will the particles go away after the filter stops getting bubbles "fed" to it? Will my filter be okay? Or does it have to be replaced now?
