Water chemistry - need help!

[Mdragger88]

Big storm/tornado watch & hail coming to Austin. Curious to see what the test tells me tomorrow...

Rain shouldn’t effect much if your fc is in target range for your cya or higher. Lots of water/overflow can dilute salt & cya.
Just get any debris out as soon as u can (when it’s safe to do so) & stay safe!

When your builder comes over, tell him to NOT dump anything into the pool that you will take care of it from here on out.

100%!!!!

Good day to you all! Tornados are gone, so hubby and I cleaned the pool to the best of our abilities (Polaris VRX iq+ incoming), and these are the new tests after very heavy rains:

03/23/2022

FC - 8.2 (25ml - 41 drops)
CC - 0
pH - 7.4 - 7.6
TA - 50 to slight pink


60 to bright pink


CH - 90 then changed to pink again, so 100
CYA - Between 60 and 70

The good news is FC is dropping nicely. pH looking BEAUTIFUL, unless something else (high FC?) is messing with the readings. TA should be 60.

I think we are going places...? I still have to wait until FC is around 5ish, I guess. What should I be doing now?

Thanks!!!

All looks good. Good job.

You have the Taylor 2006c test kit correct? Looking at your picture and reading your comments I think you might be doing your PH test wrong. You need to fill the big tube up to the 44ml mark (which is almost to the top of tube) and add 5 drops of R-004 to that and shake it up a bit. Then you compare the color to the comparator. The other test kit people have here (TF-100) uses a different ph test that uses a different ph test liquid and tube and only uses 10ml of water. Don’t confuse the directions between the two different Taylor PH test kits. I have owned both the 2006c and the TF-100 and that’s the main difference other then different quantities of certain tests.

Wohoo! I'm so happy. All thanks to all guidance from this forum

Question. According to Water Balance for SWGs my CH should be 220 -320. It is sitting at 100. Should I worry about this yet?

The pictures are not for pH. I was showing the TA results.

You have a fiberglass pool. CH is not as critical.
Do you have water line tile with grout between it?

Fantastic.

No, no tile at all. This is what I have:



Concrete deck will have a nice makeover at the end of the week, but that's all the fancy stuff we wanted to have.

 

[mknauss]

No need to add calcium. I suspect the CH will rise as you add fill water with calcium in it due to evaporation. Test and record the CH monthly.

 

[Isasate]

Roger that! I will go ahead and return the https://www.lowes.com/pd/Clorox-Poo...pa-8482-Calcium-Hardness-Increaser/1002246686 that I bought just in case

Great job!!! One more tip for you. For FC, just fill to the 10ml line. Every drop will be .5. Saves reagent and time. You don't need to be more accurate that x.0 or x.5. 41 is a lot of drops vs. 16.

Ummmmmm...swimming?

Right? That reagent bottle is looking at me like... girl, stop I thought I might want to be more accurate at the beginning.

Ummmmmm...swimming?

If the water wasn't that cold... haha!

But also, FC is at 8. Is that a "safe" level?

 

[mknauss]

It is safe to swim at FC levels up to SLAM level, or 40% of CYA level.

Baaa...This is how we swim early in Ohio. Gotta get you one...

I screenshotted this so that I never lose it in the future

Hahahah! Polar bear plunge!

I think, as a symbolic gesture, for conquering your pool, you should at least jump in. *and* post a pic.

Didn't your kit come with another sample tube not connected to the pH test block?

Nope. I mean, it comes with the CYA test bottle and the regular one. I see instructions to test salt level but I have no way to do so
