If anyone has experienced this or has expertise on the subject, feedback is greatly appreciated.
I have an AquaClear 110 about a year old that has gotten unbearably loud. I do have sand, and thought it was sand in the impeller. I took apart the impeller a couple of times and brushed it and rinsed it out but it is still very loud. If the water is still flowing normally, is it safe to assume it isn't a bad impeller?
Thanks,
Ben
