Explain to me like a child- what makes sparkling water?

Apr 14, 2013

So the other day when I checked water it was FC at 7.0 and PH @ 7.2 and the water literally sparkled.

It has stayed clear and algae free on plaster, but seems to have a bit of opacity to it. Are there particular values asssociated with sparkling. Pool store guessed without testing that it was TC, but never has been high.

Planning a pool party early next month and if I could get down the sparkle bit, that would be sooo cool.
 
Keep your test results in range as outlined in Pool School, test every day, feed the pool every day and you should maintain the sparkle. :goodjob:
 
A well running filtering system is a huge plus in this aspect too. Your numbers could be great, but still have some fine dirt in in causing cloudy water.
 
Post a full set of trustworthy (not strips, not pool store) test results and we'll tell you if chemistry is a likely cause of the pool losing its luster.

My pool loses some of the sparkle after I give it a brushing. It's like the dust on furniture - stuff clings to the walls. The water is absolutely perfect until I brush, or someone gets in and starts rubbing on the walls. Brush more often and it doesn't build up.
 
Resulting numbers are taylor numbers and not strips.

Test daily? feed daily? Ugh, I was trying to set a pattern of 2-3 times a week, the fewer the better.
It's easier to just poor in a gallon of shock than smaller amounts.

How often should I run the polaris robot. I run it about once a week.

again, water is clear and core values are good, but wondering what it takes for the next step
 
You never actually posted your numbers. Ideally, for new pool owners, you should be testing every day. After you get some experience, you can usually go to every other day or so. If you have a Liquidator or SWG or some such chemical feeder (not tablets) you can test less often. Just how often I am not sure.

Well, that won't get you much success towards your goal of sparkling water. It takes a bit more effort than you are currently willing to give but keep reading the successes on here and you might change your mind. Hope so. :lol:
 
I am assuming chemical depletion is fairly constant and am looking for a solution that will reach goal with least amount of work as one of the agreements with taking over the pool care is that it be neither too costly nor too time consuming.

Took FC and PH sample this am, the numbers definitely show the last treatment was 10 days ago.

FC was 0.0
PH was 7.8

Added 1 gal acid and 2 gal of chlorine.

Current numbers this pm:
[I had posted similar numbers in other threads, but here is the current and best for this thread]
FC 10.5 ;; yeah a little high, but also have a touch of algae, so not wasted chemicals
CC 0.0 ;; good number
PH 7.0 ;; little on low side
Cal Hardness 590 ;; don't know how to interpret this one, I think anything between 500 and 800 is good
Cy Acid 58 ish ;; lower than 60 but higher than 55, hard to determine what is meant by the point when the black dot disappears,
is it when it's smokey, just barely seen, or when totally not seen


I don't understand what makes the PH rise. My current theory is a chemical reaction between the plaster/concrete and the water is unbalancing the PH. So question is does plaster want a different PH than humans. Is it best with a PH of 7.8 or so whereas we like 7.2 to 7.4?

I've just started to chart how much chemicals we need, but it appears that gallons of shock/chlorine is between 1 and 1.5/week and acid is about 1/2 per week. I presume this is about what others see.

Am I missing any important chemical test or need correction in interpretation of the numbers?

It's over 100 now so waiting til cools before swimming...

You posted many numbers, but not your Total Alkalinity (TA). Pools are intentionally over-carbonated to provide a pH buffer and to protect plaster surfaces by saturating the water with calcium carbonate. Because of the over-carbonation, carbon dioxide outgasses from the pool and that causes the pH to rise. There is no mystery here. The equilibrium amount of TA in the pool at a pH of 7.5 is only 8 ppm if there is no CYA in the water. This chart shows how much pool water is over-carbonated at various pH and TA levels (assuming 30 ppm CYA). Note that there is more outgassing at a lower pH so the pH will tend to rise more when it is lower and tend to slow down in its rise when it is higher.

Why don't you measure and post your TA number. If it's higher than 70 or 80 ppm, then it may be too high and accounting for much of the pH rise. Also note that aeration increases the rate of outgassing so if you have any waterfalls, spillovers, fountains, etc. then those can contribute to a faster rising of pH.

And yes, curing plaster causes the pH to rise, but that slows down significantly in the first month and usually has no noticeable effect after the first year.

Opps skipped a test result. On 5/18 TA was 125, today it was 100.

No aeration, or water features, Pretty vanilla pool. I see the chart but i don't know how to interpret it. Understand about PH buffers, as do that in aquariums so the normal cycle does not turn the water acidic. I guess with pools it's the opposite.

So do I need to do something to lower the TA?
 
Taylor's manual says TA is perfect, as ideal range is 80-120

Calcium hardness is a bit high, but below the max of 1000, do I need to drain out some water?

Saturation index is -0.1 so overall balance seems ok, it should be better in a few days as ph rises and FC falls.

But still would feel better with confirmation of TA interpretation and Calcium hardness numbers.

FYI, on 5/18 hardness was 750, and now 590, don't know why it would drop, but it has. Not enough tests to know if real water difference or in differences in using the taylor kit
 
This is only my experience and opinion, I could be completely wrong....

TFP pools have that sparkly look because they are absolutely, without a doubt, perfectly clean. If there is anything in the water, whether its oils from sweat/suntan oil, dust/dirt, or algae that's not quite visible yet, all of those things block/absorb the sunlight passing through. This explains why when you brush and kick stuff off the bottom, the pool "dulls" a little bit. However, when the pool is crystal clear, the sunlight passes through the water and bounces around in there without losing any of its intensity to debris, hence the sparkle.

You can't afford 5 minutes a day to devote to your pool? Really? How long does it take to sit pool side or at the kitchen table and run pH, and FAS test? How long does it take to add chlorine or muriatic acid?

And then you waited 10 days to add anything? And now you have algae when if you would test daily and feed the pool at night before you go to bed, you wouldn't have to go through the shocking process and babysit the pool, testing it through the day and having to get up early in the morning before the sun hits it to test it again to see if you passed the 3 criteria of clear water, .5 or less of CC and a 1ppm or less loss over night. I'd of rather tested it once a day than go through that. :goodjob:

Your 5 minutes a day just turned into a couple hours of work with a shock process, extra brushing, running the filter 24/7 to clear the algae, more chlorine and sweeping.
 
" sit pool side or at the kitchen table and run pH, and FAS test? "
What's the FAS test, I thought the most important were FC and PH and the others changed slowly and once a week monitoring of them would be good.

"see if you passed the 3 criteria of clear water, .5 or less of CC and a 1ppm or less loss over night"
Well that's what I'm looking for. You say 3 criteria, but i only see 2 listed. CC doesn't change much, didn't you mean to say FC and less than XXX change overnight?

The third criteria is the water is clear. Shoulda been a colon between of and clear.

FAS test is the FC/CC test. The powder one.

Yes. Ideally it should be between 250-350, but if that is not possible try to keep the CSI as close to 0 as possible. CSI can be seen towards the bottom of poolcalculator.com
EDIT: I think I might have misunderstood the question, as happens a lot with me. 590 is not a bad CH number if you keep an eye on CSI. Just keep it close to 0 and you will be fine.

So FAS == FC + CC, and then little change overnight. this makes sense.

Never saw a response: is calcium hardness something to be concerned about
590? Hah! I scoff at your puny numbers! :viking:

High CH can lead to scaling. It will not make the pool cloudy if everything is in in range. I'm crowding 900 again and my water sparkles and I can call heads or tails on a coin dropped in the deep end.

Worry about everything else for a couple weeks, until you have the art and science of balancing down. Then worry about CH.

As an aside, there are directions for testing with high CH using only 10 ml, and each drop is 25. Who cares if you read 600 instead of 590? Close enough. Saves time and R-0012. Your CH may also not be that high...mine dropped 200 points just by testing suing the speedstir. Mixing is really critical on that test.
