Yo, check your filter. If it's clogged, it's not gonna do its job right. Clean or replace the media if it's been a while.

Thanks for the advice, everyone. I'll try cutting back on feeding and adding some plants. I'll also test my tap water to see if that's the culprit.

Good plan. Let us know how it goes. Sometimes it's a combo of things, so don't get discouraged if it takes a bit to see results.
