By the way the pool is super clean, I still have the pool guys come for a vacuum and scrubbing which they did. So hopefully no algae!!!

Do the test carefully and be consist with evening and morning test. Morning test before sunrise.
Oh boy, definitely over shot it. I checked FC levels twice, both times I got FC of 12
Turned off the SWG, removed the CYA and kept it in a bucket.
Will check in the AM.
Alright. Unfortunately missed my alarm and woke up late. I ended up testing around 7:30. Approx 2 hours after sunrise.
My FC levels are 13 now!!!
This seemed very strange to me, I checked with my pool guy on what he did to remove the algae last week. He vacuumed to waste all the green but I realized he put in sodium bromide
I don’t think he put very much in, am trying to find out specifics later today. The million dollar question is - how do I know if the bromide is wearing off to the sun? Is there any specific tests or trends I can look too?
Also, is my FC testing skewed because of this? I know the only solution to this is drain but I don’t think that’s a possibility in my end.
It’s still chilli outside. Am hoping the bromide can continually be burned up by the sun. I have left my SWG off - is there a way I can continually check FC levels and be confident when I know the bromide is at low enough levels. I will continue to dilute the water as well as I get chances to do so.

I hope you mean chlorine, not bromide. Have you been maintaining this pool with bromide? Your signature lists SWG.
Did you turn your SWG off for SLAM?

No, last week when I posted I had algea, the pool guy came and put 16 oz of sodium boride to fight it. I didn’t know anything then - it was at that time I decided to look into TFP and posted here.
I know the only way to 100% out of bromine is drain the pool - but I can’t do that. I don’t think 16 oz is too much, so am hoping to just keep testing and add chlorine and keep testing till I see considerable drops and consistency. Then will maintain, raise CYA levels etc.
I found this link that says it could take a while
Yea turned off SWG. Gonna check later today if any of this FC / Borine lowers. I just don’t know what the test result is reporting back to me.
Any suggestions?

16 ounces of sodium bromide in 34K gallons would generate (if fully oxidized) about 5ppm Total Bromine. This will eventually outgas as bromine or get filtered as combined bromine, but it may take some weeks/months. You may see higher chlorine demand.
This is great info. So I was thinking to just use LC and check levels every evening before and after the addition and try to keep them a bit elevated. Maybe 4-6 ppm. I figure the test is giving me value of FC and Bromine together (is this correct?) which is basically sanitizer.
Once I see consistent drops in FC levels I am guessing bromine has been outgassed then proceed to TFP methods.
I’ll hold off on CYA for now. Will check TA and PH levels maybe every week or so as well.
not an ideal scenario but trying to work with what I have. What do you think?
Thanks for all your advice and time answering my questions. Really appreciate it.
Tested FC today. It was 3 drops so 1.5 ppm for chlorine. I’m still unsure if my pool is bromine or chlorine at the moment.
I kept the SWG at 50% and put in about 2/3 gallon of LC. I’ll test again later but I reckon if I try to keep it at 1.5-3 ppm as per my Taylor test kit I’ll be safe. Still should be around 20 CYA as I haven’t added more conditioner.
If it’s still primarily bromine , and my test shows 3 ppm (6 drops) is it safe to swim or is that too much? I’m still trying to figure out the game plan. Am hoping in 2-3 weeks I can safely assume it’s chlorine.
There’s also this website which shows how to check if you have bromine or chlorine in the pool. In a few weeks will try this out
