Back From vacation

[poolmom06]

My BIL was supposed to be taking care of my pool and I came home to a green pool, I immediately dumped two gallons of bleach in and then tested my levels,
Ph was over 8.2
ALk was 130
FC over 10
CC over 10
I have added 4more gallons of a generic bleach tonight( all i could find in our small town convenience store)
Where do I go from here??
I added some acid to bring my ph and alk down

You really need to know your cya, so you know how much bleach to add. Please let us know what kind of pool it is, and if your combined chlorine is really over 10, and your free chlorine is over 10, then your total chlorine is over 20 which may give you false high ph readings. If you could post a full set of numbers, it would help us help you.

CYA is 30...
18 ft round AG pool,
I have added 6 big ultra bleach bottles today...

Oh, if you did put in 6 big jugs in a 7,600 gal pool, your chlorine is at about 47ppms!! You will kill anything that was in there, but your liner is probably bleached out. Your ph and alkalinity won't test right with chlorine at that level. I would try to drain some water and put some new water in to dilute the amount of chlorine you have in there asap.

Hi;
I probably would have lowered the pH some then chlorined it as I'd want to get maximum effect from my chlorine buck but that's for another time.

I owned a pool with a liner back in the late 1970's and we got our chlorine up there unintentionally a couple of times because of algae. I can't say how high it got but we seriously overchlorinated and we got lucky and the liner was just fine but then we may not have reached your level and it was an IG vinyl liner pool so maybe that's a difference too.

I wanted to ask if the BIL remember to feed the dogs and cats?

Often, when you have very high chlorine levels it gives a false reading for ph. And if she added 4 gals of bleach in a 7,600 gal pool, then the chlorine was really high when she tested for ph. You can really do a lot of damage to a liner when you unintentionally take the ph below 7, and have the chlorine very high.
