new here, want to start BBB

[Liz91899]

Hello!

Wish I heard about BBB when we installed our AG in June! Want to switch from trichlor tabs to BBB!

My TF-100 results:
FC - 8
CC - 1
PH - 7.2
TA - 80
CH - 50
CYA - 50

Any advice would be appreciated!

YOur numbers aren't bad....what does your water look like?

 

[Liz91899]

water is clear

 

[frogabog]

1ppm CC is fairly suspect however. No?

 

[257WbyMag]

Well, if you do have a CC of 1, a quick shock is probably in order. That would be what I would do anyway.

Welcome to tfp, Liz91899

I agree with the others, CC of 1 ppm means you have organics in the pool, and you need to do the shocking process.

 

[duraleigh]

While a CC of 1ppm is not good, you could actually give it another day of testing before you start the shock process.

Since your water is clear, I would just elevate the chlorine up to about 20ppm tonight and then check your CC's in the morning.

If it has dropped to .5ppm or less, there is no need to shock and you can let FC drift back down to normal.

My CC is still at 1. How slowly do I pour the bleach in the pool this evening? Thanks for all the replies.

Slow enough that it doesn't splash, do it right in front of the return and you should see the cloud spread out and disperse.

How long do I run the filter? Thanks

Generally, it's recommended you run the pump for half an hour after adding chemicals to let them mix. However, since you're performing essentially an abbreviated shock process, I'd let it run all night. If it's too noisy or whatever, run it as long as you can, and get in there with a brush to be sure it's totally mixed, no dead spots in the circulation.

Have you read ?

 

[Liz91899]

Thank you, Richard Yes, I read pool school.

 

[duraleigh]

The sun will be quite helpful tomorrow in burning off the CC's so I hope you get sun, and if so, test later in the day giving the sun a chance to work.

I've been walking around my pool with Bleach (other times Borax...) and adding maybe 1/6 of container in front of each jet. So it takes me maybe 2 minutes to empty a container then rinse. Some at each jet waiting just a bit between. Does this sound like a good way to continue adding chemicals when needed?

My TF-100 today results:
FC - 14
CC - .5
PH - 7.5
TA - 90
CH - 50
CYA - 50

I raised my FC to 20 Monday night to lower my CC: 1. Didn't test yesterday, the weather was cloudy with some sun. Is it safe for the kids to swim in it today with the FC at 14?

The water is clear? Then, yes, because FC is below shock level.

You really ought to run the overnight loss test to be sure it's all dead. Because if it isn't, you're still soooo close it would be a shame to not deliver the death blow.

 

[Liz91899]

Water is very clear. Should I shock it because my CC is 0.5 or just do the overnight test?

Sigh....

I thought you were undertaking the shock process? If not, then why do you have such high FC?

The three tests to know when you're done with the shock process:
CC is 0.5 or lower;
An overnight FC loss test shows a loss of 1.0 ppm or less;
And the water is clear.

You have two of the three for sure. All that's left is the overnight loss test. If that passes, you can let FC drift down to normal levels.

My TF-100 today results:
FC - 2.5 + CC - .5 = TC - 3
PH - 7.1
TA - 80
CH - 420
CYA - 70 I think, this is a hard one to be sure...
Water is perhaps 85% clear (been clearing every day since I started attempting BBB). Filter cleaned Sunday, showing good.

So I am thinking add a little chlorine via bleach, then a little Borax to raise PH to optimal.
How are the other numbers and advice? Brushing every day. Not much of anything anywhere except dust on shallow deck where pool cleaner does not go.

Thanks.

Richard, I misunderstood when 257wbymag suggested a quick shock. I thought a quick shock is just to raise my FC to 20 with one bleach application. I also thought my CC needed to be at 0.

My other problem is we are going away Thursday-Sunday. Do I throw a couple of pucks in the floater or have my neighbour put in bleach?
