white wispy stuff clinging to jets in hot tub

[Lynn401]

Hello. Just the past year our hot tub is developing wispy white something clinging to the jets. And ultimately all over the filters. The water is crystal clear and tests well. It takes about a month and then it's back. We have tried filling and running bleach water through jets, shocking....Once it gets to this point we have to drain and start over. IT does not look like or sound like White Mold that is more of floating particles, this is clinging to jets and if left it will become longer  wispy floating throughout water. Any thoughts ?thanks so much for any help you can offer.

Post a full set of test results (and how they were done such as strips, drop based kit such as Taylor, Meter and reagents such and ColorQ, Dealer testing and how what they used--strips, disc and meter, liquid regents)  and what sanitizer system you are using. Also, if you can, post a picture. It will really help. This way we will have a good idea of what might be going on. I am particularly interested in what sanitizer you are using and also your calcium hardness, pH, and total alkalinity. Also, if you are using stabilized chlorine such as dichlor or trichlor what your cyanuric acid (stabilizer) level is. I can think of at least 4 possible causes for what you are describing and we need to narrow it down.
