Water testing and left over trichlo

[Baketown]

Performed the CYA test, black dot disappeared at 85.
Chlorine is 1 and Ph is 7.5

So, if you diluted as Ben suggested above, then you need to multiply the reading of 85 x3 = 255.

If it were my pool and I was able, I'd probably drain and refill a good bit of that water since you have a ridiculously high CYA. But, where you live there may be water restrictions. Wait and see what Ben's recommendation is for you.

But, get some bleach in there. A chlorine of 1 is an open invitation to algae. I'd probably put about 4 of the 121-oz jugs of bleach in there.

I just entered my new test results. I dumped 4 jugs of bleach last night. I going to put in 4 more tonight. I have a cartridge filter, is it ok to be putting bleach directly in filter basket area or spread around pool? Seems as though I also need a feeder, any recommendations?

[PoolDoc]

I think the cartridge will be find, but if you like, just put one in the skimmer and the rest in the pool.

You need to continue with the 4 bottle doses daily, till you can hold chlorine overnight. After that, you'll need to achieved 15 - 20 ppm levels, in order to keep your pool algae free, given the CYA=250 level that you reported.

New test!
It appears the chlorine is staying in better but pH is down and TA is up. Both CH and CYA are down slightly.
I will continue the 4 jugs regimen tonight. As for pH, it took 6 drops to bring the color to 7.5ppm. Should be adjusted before or after adding bleach to pool. Day or night?

[Watermom]

It doesn't matter if you add bleach first or Borax but you need to test your pH when the chlorine level is no higher than 10ppm. Otherwise, you'll get a false pH reading. (On kits other than Taylor kits, the pH test is only valid if the chlorine is no higher than 5ppm.)

[PoolDoc]

Keep in mind what your goals are:

1. Chlorine levels stable overnight.
2. PH between 7 & 8 all the time; for you with high CH, 7.2 - 7.6 would be good.

3. Once chlorine is stable overnight, you want to maintain FC levels that range between 5 & 10% of your CYA level (225).
