Adding muriatic acid to a bromine hot tub

[Jschway]

I just converted my chlorine hot tub to bromine..

My pH levels were off the charts using a Taylor k 2006...

I added some muriatic acid and it turned bright yellow for a half a second...

Is this normal?

Should I be using a different test kit?

I asked the second question because I stuck some test strips in the pool and both test strips said my pH was low...

Yellow is elemental bromine.

It usually indicates that the pH is too low and the bromine is too high.

 

[Jschway]

My bromine is definitely too high!

What's the best way to test pH in a bromine hot tub?

 

[JamesW]

You can test pH with the regular reagent as long as the bromine is not over 10 ppm.

What is the total alkalinity?

50

With a hot tub, you have to be really careful not to overdose the chemicals.

What is the current bromine level?

Pool with high bromine and low pH.

"Expert" needs help. LOL

Ok, I'm stumped, never seen anything like this before. Here is the pool as I arrived. Opened by homeowner 24 hours ago. Nothing added. CAM00033 by poolmom11, on Flickr PH test came out pale yellow - not even registering. TA test registered nothing. It turned a color I've never seen. FAS DPD...

It's off the chart neon purple. So over 8

EXACTLY!

Ok. I took the tablets out for 24 hour and tested again. It's going down slowly.
Fast forward to a week later. I have put the tablets back in. Everything is starting to balance out. Have soaked a couple of times and the wife said this was smells great!
