Bought a house and got a pool

[jblizzle]

Did you add more CYA like I suggested?

How much bleach did you add? What was your FC target?

Your FC and CC numbers do not make much sense as a CC that high is VERY rare.

 

[pooldv]

No need to test PH when FC is above 10, the results are not valid.

 

[BillJ]

Is it OK to use a pool shock that has CALCIUM HYPOCHLORITE 68%?

 

[jblizzle]

Why? Bleach is usually cheaper.
You can use it if your CH is not already too high.
Note that it can cause cloudiness if your pH is too high.

 

[BillJ]

I just added some CYA.
I added 2 gals of 6% bleach and 1 lb of pool shock with calcium hypochlorite 68%.
My shock FC 10.
My testing may need some work. I may have to take the water in for testing.

I had bought the stuff before I joined TFP and ran out of bleach.
You are right on the water is cloudy.

 

[jblizzle]

Do not have the pool store test your water. It will result in confusion and we will not trust the results anyway.

 

[pooldv]

Yep, post the pool store test results in the BBQ forum. we only want to see your test results. No matter how unsure you are of your testing skills we like it better than the pool store.

 

[BillJ]

OK , will need more Reagent. The TF50 didn't have much.

 

[BillJ]

last test
CL 3.0 looked like it could be higher.
PH 7.2 or a little less
FC 6
CC 1.5
TC 7.5
CH 225
TA 60
CYA the black dot never did go away.

 

[pooldv]

How many ppm CYA did you add? Assume it is in there and chlorinate based on that CYA level, Chlorine CYA Chart

It takes a week for CYA to dissolve and show up on the test.

 

[BillJ]

added 10ppm CYA.
The water is cloudy and see some black streaks on the wall.
Need to get FC up to 10 per Chlorine CYA chart?

 

[BillJ]

Should I be adding the chemicals that show in POOL MATH?

 

[pooldv]

Probably should add 20ppm more CYA. Yes, 10ppm FC for 10 CYA. Brush the pool walls.

No, don't adjust anything else during the SLAM. We can fix those after. And actually your numbers look pretty good anyway.

 

[BillJ]

Ok thanks

 

[jblizzle]

OK , will need more Reagent. The TF50 didn't have much.

Yup, that is why we were recommending the TF-100 with XL option.

 

[BuckeyeChris]

The CYA test may take up to a week to accurately show the CYA you've added. Right now you are somewhere in the 20-30 range, I'd say just keep it there for now. Retest in a week if your SLAM is not starting to turn the pool.

 

[BillJ]

Tested today
CL 3.0
PH 6.8
FC 3
CC 1
TC 4
CH 250
TA 50
Water is still cloudy, but improving a little each day.

 

[jblizzle]

Get pH back in 7s and get your FC back up.

 

[BillJ]

So PoolMath is telling me to add 50 Oz of 6% bleach to raise FC.
And to add 79 Oz of Washing soda to raise PH.
Does that sound right?

 

[Texas Splash]

Bill, last night's FC was only 3, and by now you've probably lost a little more. 50 oz of (6%) bleach only goes-up about 1 ppm for your size pool, so I would recommend adding 1 full gallon (121 oz) of "8.25%" bleach at the grocery store. If you only have 6% available, it would be 175 OZ. That would take your FC up to about 6, but again I think you already lost some today, and you want to stay around 4-5.

For the PH, I got 74 OZ, so we're both close enough.

Hope that helps.

Eventually you might consider increasing your CYA level (once you know it has leveled-off) from about 30 to 40. That might protect your FC (good chlorine) a bit more. But wait until your CYA has a chance to show-up on your tests in a few days.
