first water test after pb turning pool over to me

[JakeP5253]

Here is where we stand.....
FC 12.5
CC 0
PH 7.8
TA 110
CH 550
CYA 50
Salt 3600
65 degree water

PB said "oops" when he saw the chlorine reading and said the guy he sent by must have added too much... I know thats high, the SWCG is turned to 0 waiting for it to lower. I am putting in 50oz of acid per pool math....where do I go from here?

Numbers aren't bad, although I question the CH. Are you using a speedstir? Is your local water hard, or did the pool guy dump a bunch of Cal-Hypo in there? In any case, the FC isn't crazy high since your CYA is at 50. It will fall slowly with chilly water, but it will fall. Congrats on the new pool.

CH of fill water is 100....im not using a speed stir yet, need to order one...do I need to add the cya right now or just let it ride as is?

Gotcha. Results with the speedstir may impact that result. Of course when a pool is competed, the builder has people dump stuff in without much effort as to accuracy. Some use Cal-Hypo, but in any case you have a great test kit and can watch it now. Continue to use the PoolMath tool (or APP) and you'll be in good shape.

Jake,

Please do us a favor and list your numbers as follows...
FC
CC
pH
TA
CH
CYA
Salt
Temp

No reason to report TC

It is known format and easy on the eyes for us "old guys"...

Thanks,

Jim R.

I have been working on lowering the PH fro a couple of days...it seems to be eating Muratic Acid....I know the bubblers and waterfall will increase ph...but it seems like I remember something about It leveling out over time...am I crazy?

No more than the rest of us. But yes, it will settle. It may take a few applications of acid which will also lower the TA as well. As the TA lowers more, the pH increase should slow down too.

Lower Total Alkalinity

A lower Total Alkalinity level can help a pool owner stabalize their pH increase. We'll explain how to lower TA with a little help from muriatic acid.

New plaster tends to raise the pH repeatedly as it cures. I suspect the high CH is the new plaster dust in the water also. Are you brushing?

Jake,

Took a couple years for my pH to slowly settle down. Then after switching to salt and adding borates my MA use has declined dramatically. Started at near 2 gallons a month, now less than half a gallon. But with borates the pH runs on the high side of the normal recommended range.

For the CH test, make sure you use the right sample size and multiplier;

25 ml sample, multiply drops X 10
10 ml sample, multiply drops X 25

Mine, too. I think it has more to go even.
