So a few months ago we started noticing white flakes in our hot tub. We assumed it was a bad filter so we would change the water and replace the filter. Generally that would make the problem go away for quite some time. However more recently it’s happening frequently and more pronounced. We thought it was white mold and started to treat it as such, we’ve used biofilm cleaners, shocked it multiple times with chlorine and have dumped and replace the water at least three times now. Each time we blow water through the jet lines and these white flakes keep coming out. Will fill the water again treat it with bio film cleaner and shock again. But still the problem persists. Has anyone had something similar? And are there any good suggestions on pipe cleaners to really get the gunk out of the Jets once and for all? Thank you! Included some pictures for reference
