I've A Very Small (650g) Pool And I Think I Overshocked It...
by J. Comensk
(Saratoga Springs, NY)
With 2-lbs of HTH shock 3 treatment.
Filter is running and was filled for first time 2-days ago but remains cloudy.
I then read where approximately 2-5 OZ of shock is needed for this size pool.
How do I fix this before dumping and starting over?
Thanks for the question
If I'm reading the question correctly, there was 6lbs. of chlorine used. 2lbs. of chlorine used 3 times.
The amount of chlorine that was used for a 650 gallon size small pool is actually enough the shock a 25,000 gallon pool.
Trying to take the chlorine level readings would be cost and time prohibitive.
There's 3 ways to get the chlorine level down:
1. To allow it to come down naturally through the sun and heat
2. Drain and start over
3. Use a chlorine neutralizer called Thiosulfate. If you go this route you'll probably use so much of it that it will mess up your chlorine readings.
I'm also thinking about the safety issue of having a chemical reading that high.
My personal advice would be to drain it and start over again using the correct amount of chlorine.
I use 3oz. of chlorine to bring a 1000 gallon hot tub level up from 1ppm to 4ppm. This is the hot tub for the YMCA.
If you start over again, 4 - 6oz. of Dichlor chlorine should do the trick. This also has the stabilizer (cyanuric acid/CYA) in it so you'll be hitting it from both sides, which is what you want to do.
Remember, for every 10ppm of Dichlor chlorine, you'll increase the CYA by 9ppm.
Hope this helps and have a fun and safe swimming season.
