Going back in the water after supershock?

[darikp]

I have to supershock my pool 25-100ppm depending on how long the family must wait to go back in and need advice.

FC- 14.5
cya >100
ph- 7.5
alk 130

vinyl ag; 10,500gal; 25 x 15 oval. avg temp 79-84


My specific question is; how long must we wait to go back in the water after a 25ppm shock as opposed to a 100ppm supershock?

Why would you shock it to 100ppm? That is WAY too high for a vinyl pool. What test kit are you using to get the numbers you posted above? How does your water look? What are you using as your source of chlorine? And what do you use when you need to shock?

Welcome to the Pool Forum, by the way!

The best guess chart indicates 100ppm FC for Shock+ with a CYA of 100-200.

water looks relatively clear but not blue; kinda has a tint to it still from the algae.
the 100ppm i'm getting from bens best guess chart.
I am now using 8.25% bleach as chlorine and shock
Previously I was another victim of unknowingly using Trichlor pucks exclusively. Until i found this forum, i couldn't understand why my levels were good and I was still getting algae.
My concern about shocking is because my sons bday party is sunday and I don't want to chem my pool unusable.

Dilute your sample and run the CYA test again. Use equal parts pool water and CYA testing reagent, run the test again and multiply your report by 2. Post the result.

I would NOT shock the pool to 100!!

Also, what is your CC?

[darikp]

ok, I shocked it to 25... I didn't do any permanent damage did I.

(Thank you kelemvor)

I did cc but kept adding drops, I think i got to 80 something and gave up; I re-run everything tomorrow

Might be a good idea to watch these testing demo videos and then try your CC test again.

You didn't hurt anything by shocking to 25ppm.
