This was with the TF 100 test kit.
The pool calculator said to put in 54 oz. of muriatic acid. I put about 1 1/2 Qts. in and will check ph again in 2 hours.
If ph is about 7.4 should I put in the bleach at this point or wait till the sun is off the pool this evening.
Just want to quickly point out - I verified this calculation on the pool calc. I came up with 40 oz of Muratic acid, 54 oz of dry acid. You want to be careful when you are calculating that you are using the correct dosage per chemical and you don't make mistakes on overdosing of chems. But since 40 oz comes out to a little over a quart I think you'll be okay. I just want to make sure you are getting comfortable with the Pool Calculator and confident in your calculations.
Yes, retest the PH. It should have come down (hopefully not too low ) and you can go ahead and add the bleach to bring you up to shock level, for a CYA of 30 that will be 12. Then follow the instructions in How to shock your Pool; frequent testing (up to hourly) and bleach additions to hold the shock level of 12 will mean the pool will clear quicker.
Wait to retest the CYA for a few days, sometimes it can take several days for it to fully dissolve and register on the tests.
Tested again at 1 o'clock and ph still 8.2. Added more muriatic acid.
Will test again at 3 and go from there.
Looked at the muriatic acid jug. I might of got the wrong muriatic acid as there is no percentage and it is the enviormently friendly muriatic acid the label still says it will reduce ph in pools. Learned a lesson that time.
Please point out anything I do wrong as I would like to learn what to do so I don't have to be such a bother.
It's no bother, really . You are doing fine. If it doesn't say 31.45 % on the label, you should go back to the hardware store and get the "good stuff". That's probably the really weak variety.
Went and got the good muriatic acid and put about 1 qt in at 4 o'clock and checked ph at 6 o'clock and it was down to 7.8. Added about a pint of the muriatic acid and will check it in the morning.
At 7 o'clock I added 6 of the jugs of bleach from walmart and at 9 o'clock checked the cl and still had at least 5ppm I will recheck cl in the morning and use the other test so I will know how high the cl is.
The CC is normal right now, and it will go down as you continue shocking.
You know you are done shocking with the FC holds overnight and the CC is .5 or less.
Yes, correct it now. Go out about 6 pm and increase the PH to 7.2 with Borax (predissolve it in a bucket of water and pour in front of the return, brush the pool near the return). Don't add any bleach yet.
Wait an hour, retest the PH. If it hasn't come up, add more borax to reach 7.2. You don't want PH sitting too low.
Once the PH comes up to 7.2ish, then you can start adding the bleach again, raising it back up to shock level.
Put 1 box of borax in pool and nothing else. Didn’t know whether to put bleach in too because ph was low so I didn’t.
Tested 6pm
Fc 1
Ph 7
Put ½ box of borax in pool and tested ph again at 7pm.
Ph7.2
Added 4 large jug of bleach. Tested water at 8pm.
Fc 2
Should I add more bleach tonight or wait and test in the morning?
Have to work tomorrow. If the ph is low in the morning can I add borax and a few minutes later add bleach?
Feel like I went back a little today (didn’t know whether to add bleach this morning or not as ph was low and could not post and ask) pool looks a little greener than it did this morning but still working on it.
Yes, put in more bleach tonight, target your shock level.
Yes, if PH is low you can add borax in the morning, wait a few minutes and add bleach.
You're doing fine, when the FC drops down it is sort of a step backward. The more often you can check and add bleach the quicker it will clear. But considering the PH issue I would have done the same thing.
