Let TA rise naturally?

[GMTK]

Was out of town for a week, Ph was high and wife misunderstood me and put in too much muratic acid in the pool. (and this was COMPLETELY my fault, not in any way shape or form my wife's fault, no way).

Sunday:
FC 4.2
TA 40
CH 420
PH 7.2
CYA 45

Monday
FC 3.0
TA 40
CH 400
PH 7.2
CYA 45

Can I just let the TA rise naturally or do I need to add baking soda? App says to add baking soda but I didn't know, with the weather warming up, if I can just let it rise on it's own.

G,

TA usually increases because of your fill water. I'd let it ride for now and see if it comes up on its own.

That said your FC is too low. With a CYA of 40 your target is about 7ppm, or so. The idea is to keep your FC at your target level or higher, and not somewhere between your target and the minimum.

Thanks,

Jim R.

Thanks! I actually put in a gallon of 10% this morning before work.

You wanna be happy, or right ? There are 2 entirely different outcomes here.

FC 4.2

Switch to 10ml samples and each drop is 1/2 FC instead of 1/5. The point whatevs is useless. I wanna see the 7 or the 8 when your minimum is 4 with a CYA of 50 (don't forget to round up that 45).

Whether the FC is 7.2, or 7.5 is meaningless. 7 is great. 8 is greater. 9????? Oh my. 9 is my jam.

In the past couple of years, based on a recommendation from this site, I’ve started maintaining TA in the 50-60 range to help control pH rise. It has worked surprisingly well. If you choose to do the same, you may benefit from your mistake.

Good call on going to the 10mL sample. (I got 4.2 just based on the calculator. (21 drops x .2))

For example, at my house, i'd be upset it's a 4.

A 4.2 or 4.8 does zero to make me happy about it. Might as well just call it 4.5 with the smaller sample and save reagents.

Pat the test kit on his little head and thank him. Good boy. No time to talk, we need FC and STAT.

It helps to test and know your fill water makeup, especially TA and CH, as that's part of what goes into the pool and adds to chemistry.

Yep, our water in San Antonio is VERY hard.

I just love this part so I wanted to post about it.

Thanks for slapping me in the face. Why have I not thought of doing this

My fill water is TA=260, so it's always a factor on my mind.
