I'd read a forum before I registered that gave advice for a 17,000 gallon pool. The problem the original poster was having was that live algae was plugging up the DE filter. Responder advised bypassing the filter so that there is circulation, then pour six gallons of household bleach in each day for three days in order to kill the algae. If ph was below 7, responder advised to add 8 boxes of borax.

I have a 40,000 gallon in ground pool. I wanted to know how those dosages changed for my pool.

Thanks,

Pam
