Another trying to decrease TA

Getting there with the FC CC and CYA

FC-.5
CC-2
CYA-50

Adding another 2 gallons of bleach tonight to see if it gets me there. Then I guess it’s back to trying to get TA right and double checking everything else again.

No more CYA until you get the chlorine under control.

Ignore TA, it's not important.

With high CC and an inability to keep the FC up you have something organic in the water consuming chlorine. You need to follow the SLAM process until it's is complete.

Did I say, ignore TA? The only thing to worry about right now is -

Get pH to 7.0-7.2 You will not test pH again until the SLAM is complete

Add liquid chlorine to get to your SLAM level and keep it there.

Test and add chlorine as many times a day as you can.

Ok everyone. These are my latest numbers. Thoughts? We have been dumping gallons of 7% Clorox bleach in, but doesn’t seem to go above the .5 range.

FC -.5
Cc-.5
Ph-7.2
TA-200
Ch-270
CYA-50
 
Top fox,
Are you sure you're calculating the bleach correctly. What's the date, maybe it's old and lost its punch. Are you sure you're testing with the correct amount of water. Something is off here.
 
Keep pouring in chlorine until it begins to hold. But, that doesn't mean 5 gallonns at once. Target 5 for now and see how it goes.

It may not look like it from your perspective, but you are gaining ground. Your cc have gone form 3 to .5

There are several reasons why this can happen, but the solution to all of them is chlorine to knock out what is in the water.

At this point yu only need to be testing FC/CC until yu see the chlorine start to hold.
 
Thanks. Yeah FC and CC have been my focus. All the bleach is new. Been buying it as we can find it. Hasn’t been super easy to come by with am this COVID mess. Think I have another 3 gallons currently at my disposal.

Ok everyone. This broken foot has really slowed me down. This is where I’m at now

FC-4
CC-0
CH-220
PH-7.4
TA-240
CYA-50

So I think we are pretty good minus TA, which I still don’t get as I keep dropping the PH to 6.8-7.2, but it doesn’t seem to budge TA much. I plan to put some more CYA in and think I’m in the low range for CH. Have pretty much figured out through this process that 4lbs of stabilizer raises the CYA in my pool 25-30.
 
That’s correct. That said - high TA isn’t inherently dangerous unless it’s making your CSI too high. You need to know what it is so that you can calculate how much acid to add to lower the pH, but if you let it just rise to 8.0 over time and then drop it down when it gets that high, you’re doing fine.

The importance of CSI in Virginia is minimalized, CSI is meaningful for folks who cannot maintain pools within TFP guidelines unless you use extraordinary measure (Arizona, parts of California and Texas.)
I did check it out before. In a nutshell if memory serves me right itbasically was saying lower ph to 7.2 or lower, aerate to raise ph, then repeat.

So, are you saying that didn't work?
 
Previously doing that didn’t really change anything with TA, but my other items like CYA, FC and CC weren’t right either. So maybe with my other values being good, it will work this time.
 
Try it again. (you other values are not relevant). I would carefully lower down to 6.8 and then aerate as vigorously as you can. It will start to become ineffective as you approach 7.8 or so, Be prepared to lower it down to 6.8 each time until you reach your target.
 
Hey everyone,

20x40 Salt Water gunite pool with white plaster, approx 28,500 gallons. 3rd season, first managing myself. Been fighting high TA for a month, but otherwise things have been pretty good. Latest numbers are the following:

FC-4
CC-0
PH-7.4
TA-170 (first time in a month it has been below 200)
CH-310
CYA-80
Salt-3500

Pool gets tested once a week for all values. Pool gets brushed on the same day. Filtration system pressure is in clean zone, Chlorinator all green lights.

I noticed today my two pool stairs and my swim out ledge are now rough. I’ve only been in the pool twice this season,and didn’t notice it the first time in, but doesn’t mean it wasn’t rough then. Last season it definitely wasn’t rough. Have I done something wrong to cause this? Is there any easy way I can remedy the roughness?

As always thanks!
 
CSI is fine so should not be scale. Can you get a sample of it?

You are riding at minimum for FC. Might want to ride Target for your CYA.
 
Our CYA is 90 and our target FC is 10-12. ** corrected information, evaporation does not lower CYA ** Currently adding +/- one gallon a day of 10% liquid chlorine to maintain 10ppm FC.
We've also been slowly lowering the TA via the muriatic acid/aeration method.

Bought some wet/dry sand paper. A couple of swipes with barely any pressure smoothed things out. Definitely going to keep an eye on it though and see if it happens again.

Back to trying to drop this TA. :)
 
So noticed my pool has more rough spots around it. Noticed additional today my chlorinator is now saying my salt is high salt. Measured at 3850. So guessing that is maybe what is causing my rough issue. Pool calculator says I need to drain 6% of the water.

Is there anything else I can do for the rough spots without having to sand all of them?
 
Didn’t notice before, but now that I’m draining water to get the salt level down I see basically a white ring around the pool on the water tile. I assume this is calcium scale? My CH has been in range and my ph has been kept in range/low while trying to get the TA down. Did I miss something else that I should be checking?image.jpg
 
Here is my latest numbers

FC-4 (yep working to raise this)
CC-0
PH-7 (working on lower the TA, which is why lower)
TA-190
CH-310
CYA-50
Salt-3850 (draining water and refill to lower. Not sure how this rose, considering I was spot on for weeks with what my SWG said was ideal 3600)
