Hi, whenever I seem to do a water change these white worms appear in my tank, now Ive heard theyre a sign of bad water but I have good water (tested it a few times) and they only ever appear in this mass when a water change is done.
What are they and how can I get rid of them? Ive cleaned the filter out before and theyre still here
Photo shows the worms all over the water
