Foam in Spa

Today I added some liquid bleach & muriatic acid to my 2500-gallon inground spa with the pump running at about 3,200 rpms. Nothing unusual. However, for the first time, I noticed that there was a layer of foam bubbles on the surface of the water as the jets were running. When the jets were turned off, the bubbles disappeared. In the 5 years that I have had the spa, this was the first time this has occurred. I might add that the rest of the chemistry was spot on.

Could someone kindly give me an explanation? Thank you so much.

What brand liquid chlorine did you use?

Was it pure liquid chlorine with no additives? Additives such as fragrances, thickeners (splashless), or surfactants (outdoor bleach) may cause foaming. Bleach with fabric protectors (chloromax technology) may also cause foaming.

U have to be careful now when buying bleach- as even some store brands have “fabric conditioners” etc. I have had no luck during covid finding any that didn’t have “something” in it. Been sticking w/ Walmart/lowes pool essentials 10% or 12.5% from the ps

I bought a generic store brand bleach (Winco) which is a 7.5% solution. No listed fabric conditioners, no non-splash, no scents. Hopefully this will eliminate the foaming issue.
