Looks like a nice place to chill (both figuratively and literally!)... especially on these 95 degree days! Hopefully the fountain is helping to keep your water cooler.

yes it does help to keep the water cooler. I just completed it this morning but it helps much better when you run the fountain during the night.

My numbers for today are

FC = 2 added 60 oz of chlorine to raise FC to 9+
PH = 7.8
TA = 110
CH = 120
CYA = 60

CYA when up when I added CH
PH went up because I am using my fountain to cool the water

CYA would not go up when you added calcium. They are unrelated. You either measured differently this time or more CYA has dissolved. Or you have been using powdered chlorine or tablets and not liquid. But calcium would not raise CYA.

Lower your pH to 7.2 and then let it drift back up to 8. Then repeat. Eventually your total alkalinity will fall and your pH won't rise as fast. The total alkalinity guidelines assume you are using tablets which are acidic... you should be using liquid chlorine which is pH neutral.

Those tablets add calcium to the water. Your choice: Pool store method or trouble free pool method. Can’t do both.

How absolute is that statement? Is there not a place for those sort of tabs for a vacation and then get back on the program after a return? Otherwise, and without a liquidator, there's no real way to leave town for a week or more.

TFPC is about understanding what you are putting into your pool and how to do it inexpensively. So yes, there can be a place for tabs, etc. so long as you appreciate and account for their effects.

I suppose I was being extreme, but if you look back through the post history of this thread, you will see that the original poster asked why should he not use trichlor tablets... and I explained that they add cyanuric acid and that liquid bleach was better.

Now he asks... well, why can't I use these "other" tablets "without cya?"... (in this case, cal hypo)....

And I then received a private message from OP asking why he is having to use so much bleach each day....

So... I suppose one could assume that OP is thinking... boy why should I have to test and add bleach every day when I can use these tablets AND they won't add stablizer to the water...

My point is, the grass is not greener on the other side. The tablets are not the solution to your problems. You need to figure out what your issue is and not just search for some other way to chlorinate your pool... Especially not calcium based tablets in Texas with constant evaporation and hard water....

I understand the SLAM but if I have algae or other contamination in the pool, shouldn't my pool water be cloudy, my water is crystal clear.

Well, there were a few times I think when your chlorine got below the minimum? Or am I mistaken?

You may have a very small little colony of algae growing somewhere consuming chlorine and the only way to know is to perform the overnight test.

You want to catch it before the pool turns cloudy or green... One of the first signs you have things growing in the water is that the chlorine usage spikes...

The overnight chlorine loss test rules out ultra violet light as a source for chlorine loss. If you are using a bunch up overnight with no sunlight, you have something growing in the water.

If not, then we know we have at least ruled that out.

I usually run my water tests first thing every morning and then add what I need, between the time I add chlorine that morning and then test it the next morning is when I see the drop in the FC or should I be testing every night. I will try to preform the Overnight Chlorine Loss test tonight as I have to be at the VA Hospital very early in the morning.

If you can't do the test tonight, it's not an emergency.

You should see about 1-4 ppm per day loss. If anything above that, you should look for alternate causes.
