my pool is fiberglass 6500 gal test results no chlorine showing ,PH below6.8, alkalinity below 20 ppm using a Pentair test kit but have ordered a taylor 2006c test kit thanks Jarsch

The most critical problem you have right now is low pH as any reading below 7.0 is acidic and can damage your pool! We normally recommend using 20 Mule Team Borax (laundry aisle at Walmart) to raise the pH. However, since your alkalinity is also low, you can use Arm and Hammer washing soda to raise both at the same time. Add it slowly to the skimmer, breaking up any clumps, while the pump is running. I'd start with a fourth of a box at a time. Wait a few hours, retest, redose until you get your pH between 7.2-7.8 and your alk between 80-120 or so. (Just an FYI, if you need to raise pH only and not alk, you use Borax.)

Also, get some bleach in there per Ben's instructions before it turns green!

By the way, you can work on pH, alk and chlorine at the same time. No problem.

Good decision buying the good kit. As soon as you get it, post a set of testing results. We really need to know the CYA level to pinpoint our advise more accurately for your pool's chlorine requirements.

Let us know if you have more questions.

If you can get your pump running add borax slowly to the skimmer, a box every 30 minutes, till you get your pH over 7.0.

Hey thanks you all are great thanks for the advice will get back as soon as i get new test kit and new readings have a great day Jarsch

Hey: Thank you all . I had this pool (fiberglass,6500 gal, in ground chlorine sanitizer ) 10 years . This year is 1st year not stressed because of your help. Received my Taylor 2006c test kit love it. Ran test today results - chlorine none ( put 2 gal. bleach 2 days ago) ,PH 7.8-Alkalinity 80 PPM-Calcium Hardness 150 PPM-Cyanuric Acid 80 PPM. Am trying to balance before opening the pool have pump running cover on. What do I do next? Thanks again Jerry

[jarsch]

Forgot to mention I use Trichoro auto despenced. Thanks jerry

[PoolDoc]

You don't need to 'balance' anything; your pH and CYA are on the high end, but not anything you have to change right now.

1. Get a cheap OTO / phenol red kit, in addition to the K2006. You can get the Taylor K1000 (click-pic for Amazon)

or buy something locally. (You'll use this to keep from using up your K2006 unnecessarily.)


2. Check your chlorine in the PM; if the chlorine level is not dark yellow (> 5 ppm) add 1/2 gallon of bleach.


3. Read the Best Guess page (in my signature) and the Muriatic Acid sticky.


4. After you have done so, decide whether you want to use muriatic acid (bought locally) or sodium bisulfate (bought from Amazon or locally):
. . . OR . . . (click-pic for Amazon)


5. Think about whether you want to run a high CYA / high chlorine pool (1x per week chlorination -- but really weird looks at the pool store) or a conventional pool.


5. Don't use any more trichlor -- or that feeder -- till you decide.

I have muriatic acid how much should I use also what is a high CYA / high chlorine pool (answer 5 ) Thanks jerry

[PoolDoc]

Basically, a pool operating in the last row of the Best Guess chart.

Operating with CYA that high, you also have to run high chlorine. But the high CYA allows you to 'bank' lots of chlorine in the pool water, with the result that you can add chlorine just 1x or 2x per week. This makes going on a week long vacation a snap.

However, if you let things slide, and get algae, the algae killing doses of chlorine are very high, and take weeks to drop. The work-around it to use small, carefully calibrated doses of sodium bromide, which creates an unstabilized bromine residual to kill your algae.

If you keep want to use up your trichlor, you'll have to either run high chlorine/high CYA or drain, and draining can be hazardous to your pool if the ground is wet, or if you have a liner pool.

what is a CYA/high chlorine pool ? Thanks jerry

================================================== =====

I like the triclor so i guess i drain water a foot or so at a time untill i get CYN down .Is their any way to us a auto dispencer with out using triclor?
