What’s this white/yellow floating chunky stuff?

[InheritedASpa]

Water is < 3 months old. Test strip within range for 7 things inc bromine, acid, ph, hardness

Only stuff I saw when searching was related to Ahhsome jet cleaner, haven’t used any special stuff besides pH raiser and typical bromine amount.

Any thoughts what the floating stuff is? How to get rid of it? Treat it? Prevent it? Etc

That looks like the BIO-FILM that comes out after an AHH!SOME purge. Have you purged you SPA recently or ever?

And can you fill out your profile so we know what spa you have.

We don't trust test strips. Do you have one of the recommended test kits? Test Kits Compared

That tub needs a purge for sure.

That does resemble biofilms.
The cure for biofilms is an Ahhsome purge then drain & refill.

The prevention for biofilms is regular Ahhsome purges then drain & refill every 3-6 months along with adequate sanitation in between.
All brand new tubs should be purged as biofilms can form in the plumbing while the tub is in transit to you since they are wet tested at the factory.
