New Pool

[BigDave]

Congrats! The k-2006 will help you control your pool and maintain your liberty.
For now, put away the acid and base demand tests and the book and the wheel. And don't frown

What was your pH reading?
How have you been chlorinating?
How does the pool look?

Another half box of Borax poured slowly in the skimmer will help raise your pH.

Hi Dave,

The pH was just barely 7, and I have not added any chlorine although I have an inline auto feeder. The water is crystal clear.
I have some pH up from Walmart but it has been raining steady for 3 days (added 1/2" to pool level) so haven't made any adjustments or readings since it started.
By half box of Borax you mean 2lbs?
thanks for you help

[BigDave]

Yep 2lb - but what I meant was about/around 2lb. You don't need a scale. Measure - treat - measure - treat ... is the process we promote here. Put in less than you think you need at a time, wait for it to mix, test and re-dose. Try to approach your treatment goals slowly to avoid going over. Calculating and dosing all at once sets us up to see-saw and chase numbers which is not as much fun as swimming.

Is the pH up you have Sodium Carbonate? Add about a pound (instead of 2lb Borax) at first. It will also raise your TA.

Your cl feeder is on and has trichlor pucks in it?

I added about 1lb of Sodium Carbonate (pH up) yesterday. Then it rained a ton.
The feeder is NOT on, and the tablets (3" trichloro-s-triazinetrione tablets) are still in the car, lol.
Chlorine dropped to 6ppm.
pH is 7.6 now after adding and waiting approx. 24hrs to retest.

I have no Combined Chlorine reading still. Is that a problem?

looking good i think.

You don't WANT a CC reading, or rather, a reading of CC=0 is optimal. So, no, it's not a problem.

You need a source of chlorine. If you don't maintain chlorine, your pool will go green again. You can use tabs in your feeder for a while but when your CYA reaches 40-50, it would be best to stop the stabilized chlorine and start using bleach.
