Ph is ideal, alkalinity is semi high

Postby Mikethemiz » Fri 14 Jun, 2013 14:56

Hello everyone! Well before I get into it, I would like to introduce myself.
My name is Mike, and I am a first time pool owner. Live in California and just trying to figure all this stuff out lol..

Ok so here are some things about my pool:

ph is 7.6 and seems stable so far.
Alkalinity is 130. And what I'm reading is this is out of range.

How would I go about dropping my pools alkalinity to 100 and keep the ph at 7.6?

Also, my pool water is pretty cloudy. It's blue, more like a sky blue. But it's pretty cloudy were as I can't see the deep end only the shallow end floor.

My pool is also about 20,000 gallons inground.

Thanks in advance for any help or tips :)

If you want to lower your TA then follow the procedure in this post which is a sticky in this forum. However, if your pH is fairly stable, then you may not need to lower the TA.

If your pool is cloudy, you might have algae, but you really need to get a proper test kit to know what is going on with your water. The Taylor K-2006 (not the K-2005) is the best kit to get or the TF-100 which uses the same reagents but is more economical (some differences as described in Test Kits Compared.

While waiting for your kit, you can shock the pool with chlorinating liquid or bleach (unscented, plain).

I agree wit Richard.
This time a year if your water gets cloudy and your alkalinity is not too high, shock the pool!
And give it a good dose!
I would not hesitate to give it 30% of CYA present in the water. It is always cheaper now, than later.
