White soft growths in spA

[Tagajjar]

Can’t figure out what these are. They grow on the sides and are white and a pain to scrub off. Kinda squishy lol.

Possibly White water mold.
It is a fungus that forms biofilms to protect itself.

How are u currently sanitizing this spa?
Is it a standalone tub or is it connected to your pool plumbing?
Do you have any current water test results from a Taylor k2006 or Tf100/pro?

Currently sanitizing with Spaguard has a bromine floater in it but never registers any sanitizer so ma manually dosing it. It’s on standalone plumbing. New filters according to test strips it all reads on point but I’ll get water tested to double check.

Doesn’t appear like any mold pics I could find. I can scrape it off and it comes off in one piece. Water isn’t cloudy or anything

Testing bromine?

I have a Taylor K-2006 test kit. I just filled my hot tub a few days ago, can I test for Bromine like I would chlorine? Use dpd powder and reagents? I realize it would be easier to just use chlorine but I would really like to use up the bromine(sodium dichloro-s-triazinetrione 82.5% sodium...
