Back from vacation, high chlorine

[butchcassidy]

Before leaving on vacation, I dosed my pool to around 20ppm FC (I thought), placed pucks in the floater and covered with winter cover.

Just got back to a clear pool with the following test results.
FC-40 (may be more, never really went fully clear)
CC-0
TA-70
CH-150
PH-7.2
CYA-40

the CH test produced green/yellow(high chlorine) and isn't accurate but tested at 150 before vacation.

What should I do to get back to swimming? Do I need to partially drain or wait for the sun to cook it out?

TIA
Butch

Just leave the cover off and the sun will bring that FC fairly soon.

I am curious, 5 pucks fully dissolved in your pool volume would add 20 ppm FC. How many pucks did you put in the floater?

I think I had 6 in there. When I pulled the floater I had about ¼ of 1 left. I never tested before leaving. I was having a small algae battle and was following SLAM when I left and then tossed in a gallon when I went out the door.

You definitely gave the pool the nuclear option.

I might have overdone it. But it sure is clear

Hope the liner still has some color ----

Going forward, what should I have done differently?

My thinking was that the small plume i was correcting would eat some of the extra, bringing it under SLAM levels and the pucks would maintain until i got home two weeks later. Before leaving, I was adding 130+ oz of 10% daily (3 days) to maintain SLAM.

In the future, you can just bump up to slam level and cover the pool if you have to leave town. You don't need extra in a floater, if the pool is clear.

The cover prevents most of the FC from being consume by the sun. After being my pool to slam level the FC takes about 5 days to drift down to target if I leave the cover on.

Marty and Pat, any reason why the OP should not use hydrogen peroxide to bring his FC back to SLAM levels?
I understand it is not recommended because in most cases it isn’t really necessary.

FC will drop rapidly with sun on the pool surface. Should be below SLAM level in 2 days or less.
