1st results!

[bryansanders]

Ok so I got the TF-100 in today and tested my untouched pool and this is what I got:

FC 0
CC 0
PH 7
TA 5 drops pink up to 20 drops pink, stayed the same... so 50?
CH 75
CYA 20

Looks like I need a little bit of everything!

 

[northrn]

All I see that you need is a little bit of CYA and some bleach.

then

Let's get that PH up a bit too please. That CYA level is too low for OK. 40 or 50 I'd say. See the cya/chlorine chart in Pool School.

 

[bryansanders]

Ok so according to poolmath I need to add the following:

1 gallon and 3 cups of Liquid Chlorine
4 lbs 3 oz of stablilizer (sock method)
and 6 lbs 3 oz of borax

Am I correct?

 

[pooldv]

Good plan! The CYA comes in 4lb jugs, I wouldn't buy another for the extra 3 oz. In this case you might use soda ash to raise your PH and raise the TA a bit at the same time. Wouldn't hurt to get it to 60 or so.

I don't mean to hijack, but how do you know that for the specific location of OK? I missed that in pool school. Forgive me, I am still trying to learn. I see the CYA chart, but nothing about location.

 

[pooldv]

All of OK is hot and sunny so the higher end of the recommended CYA range is more appropriate. Sort of like the planting hardiness zones. Up north starts at 30 and down south is 50.

 

[bryansanders]

I'll keep that noted pooldv! Always appreciate the advice. Ok so once I add the needed chems, how long do I wait to test again? and do I perform all the tests?

duh. I was overthinking it. Got it now, thank you!

 

[bryansanders]

Soda ash, how much, the remaining 3 oz?

 

[bryansanders]

...ok so I put in 1 gal 3 oz of bleach, a sock full of stabilizer 4 lbs (wont fit in my skimmer, so it is hanging in the water by the skimmer), and 3 lbs 5 oz of washing soda (dissolved in pale, then slowing poured in).

Running the pump on high, 14 psi..

When do I test again, and do I test all but the CYA??

 

[ozdiver]

You can test for all but CYA an hour after adding.
CYA you need to wait a week for full effect, so hold off testing that, it's a waste of reagents.

 

[bryansanders]

After 2 hours of adding the above, I tested TC, pH, FC, CC, and TA...

Yesterday to Today
FC 0 to 3.5
CC 0 to .5
TC 0 to 4
TA 50 to 60
PH 7 to 8.1

On the right track??

 

[ozdiver]

Looking better.
FC is ok but will have to be increasd as CYA increases.
pH overshot the mark a little but don't overdo any further adjustment as the CYA will bring this down some.
TA is a little low but while there are so many things changing I would not worry about it too much yet.

 

[bryansanders]

Ok. Great to hear. So what's my next step...wait a week to check the CYA...or perform the same test tomorrow evening?

Another thing, should I keep the pump on high?

 

[ozdiver]

Test tomorrow for FC & pH for sure.
You will likely need to add bleach and I will predict your pH will drift a little lower.

 

[bryansanders]

Sounds good, I'll post the results. Gonna be hot the next few days.

 

[pooldv]

Run the pump on low, pretty much always run it on low unless you are vacuuming or something.

Go ahead and assume that however much cya you out in the sock is in the pool and chlorinate accordingly, Chlorine CYA Chart

Here is a schedule, Pool School - Basic Pool Care Schedule

 

[bryansanders]

Retest FC 0 pH 7.7, pool walls were slimy last night, pretty sure that's where my clorine went...

Did pool math and added the required amount to get back to par...we'll see in an hour!

 

[bryansanders]

Now we are at:

FC 4
PH 7.7
TA 70
CYA Sock still dissolving.
