High CC

[woitkowski]

Hi All,

I have high high CC (2.0). I have a 20ft x 40ft inground - 30,000 gal I think. Any suggestions? Do I need to shock?

TIA, Steve

Welcome to the forum. :lol: Can you post a complete set of test results?

Welcome! When you post the test results, also indicate how you got them: Taylor kit; TF-100 kit; strips; pool store . . .

Welcome!

How's the pool look? Clear? Cloudy? Green? Solid enough to walk across?

Did you just pull the cover off before testing?

I'm using a Taylor K-2006

This morning's readings:

Ph 7.5

TA 130

FC 3.6
CC 2.0

CYA 80

CH 90

Water is clear. No algae at this point. FC seems tough to keep up lately - I have feeder wide open.

Thanks for all of the replies!

Short answer: yes, you need to perform the shock process. That CC is too high. For that matter, so is your CYA level and you're making it worse if you're using a puck feeder!

You will be seeing algae soon if you don't get on it fast! Nip it in the bud!

How do I get the CYA down? Change out water? If so, how much?
Liquid Shock or Granular?

When you say "you're making it worse if you're using a puck feeder" -- Are chlorine feeders bad? What should I be using?

The only way to lower CYA realistically is by draining and refilling. Tap water has no CYA, so the math is pretty easy.

Liquid shock or plain Chlorox bleach (or store brand equivalent - check the strength %) is what you need.

I will read -- thanks.

I read "How to Chlorinate Your Pool". Is this a good plan?

I'm going to drain some water (to the return), and refill.
Use liquid shock (have to figure out how much).
Will test everything again afterwards.

Going forward I will turn down the puck feeder and use a maintenance regimen of liquid chlorine (need to figure out how much).

If CYA doesn't go down enough, I'll repeat the drain and refill thing again.

Does that sound like the right thing to do?
