Stupid Question No. 1

[chattavan]

Did CL test and it turned orange, no yellow tint at all. Tested tap water and it remained clear, no yellow there, either, but not orange.

What does orange mean, super-duper CL, way high?

What are you using to test with? How are you adding chlorine to your pool?

TF test kit; chlorine added by salt-water generator

 

[proavia]

Use the FAS-DPD test - R-0870 and R-0871 reagents.
Use the 10 ml sample size.

When using the comparator, any color darker than the darkest yellow color just indicates that you have more than 5 ppm. That test is more to tell you if you have chlorine in the water or not. The comparator is included more for the pH test side of the comparator block.

Orange is the 10+ range from lighter to darker as the yellow is for 0 to 10. It's not dead on, one of my 3 batches of reagent went orange at 8.5, but it's an idea that FC is near 10 or above.

I've never seen it, but supposedly it goes brown at 20+

So, if the CL's so high, what's the strategy, just turn the SWG off?

Chat,

What is your CYA level??

Unless we know your CYA level, we can't tell if your FC is too high or too low.

FC/CYA Levels

SWCG's have no brain.. You have to be the brain for them. You must routinely test, and then adjust the cell's output and/or the cell's run time, so that your FC stays in your target range.

Thanks,

Jim R.

Lets back up a step and get a full set of test results put like this:
FC
CC
pH
TA
CYA
CH

Lets back up a step and get a full set of test results put like this:
FC 25
CC 3

TC 28

pH 8.2 (exact color match)
TA 13-150 (pink to red)
CYA -0- (tried twice, stayed clear to see dot at bottom both times)
CH 200

Input appreciated. Gonna hit pool store for "pH Down" salt, what else do you recommend?
Thanks

 

[chattavan]

Also, this pool is basically covered whenever not in use, so not sure CYA reading makes any difference, given the high CL level

 

[Griswald]

The CYA reading is the most important one. It alone tells you how much chlorine you need.

 

[kimkats]

Leave the cover off tomorrow if you can. That will help lower the FC. We are not going to mess with the pH for right now as it does not test well with FC that high.

We need to get some CYA in the pool for swimmers comfort. Here is the chart for the CYA/FC ratio.

pH down contains sulfates, use muriatic acid to lower pH.

pH fell into range, but I shut off the SWG and now it's -0- CL. So, I turned the SWG back on 30% and we'll see in the morning. It will run 8 hours tonight.

Good, solid plan right there!

Sorry I have not been on the boards. The hurricane went right over us. No damage but still no power.

Good to hear you're safe and sound. CL came back up to low end after first day. I'll be checking and adjusting way more often, now. Thanks so much for your input.
