Hope you're there Marie ??

I know how frustrating it is A couple of seasons ago, I kept the stain dance going. Last year I hardly had any stains. This year I had a lot of stains at the beginning, but now I haven't had any bad ones since putting in some ascorbic acid. I do find that using pucks or calhypo seem to add to stains. I have my cya at around 60 now. I am still not sure why sometimes the sequestering agent works, and sometimes the stains keep coming back no matter how much is in there. Every time I see some stain start, I take my ph back down, add some sequestering agent and they go away. I try to keep my chlorine at the level of the best guess chart. It is a balancing act, and sometimes the stains don't come off with the sequestering agent. I then just add some ascorbic acid around the perimeter of the pool and they disappear without taking the water out of balance (just lowers the ph a bit). I do keep my filter running 24/7, I think it may help with staining, but not much. I wish I could be of more help, but it is just not an exact science. I will keep trying to find out what works, and if everyone with stains posts what works for them we can learn from each other.

As the day wore on (cloudy but warm), the CL dissipated as expected ALONG WITH the green tint !!!...once the green disappeared, I check the CL which read 1.5-2...

just dumped a qt of 6% which should raise it to just above 4ppm...i'll see what happens...

How is it going?

When you get a chance post an update.

Please include full water make up,fc,cc,tc,alk,ph,cal,cya. Please also include your Pool size, liner, and filter type.

Yes, I would be interested to see if the stain came back with the additional chlorine. It is how we all learn It is always good to post a current set of numbers

Perhaps because it's Father's Day, things are looking up for me...Got POUNDED with rain last nite (sure you saw the same Marie), and thought i'd wake to a nitemare...Fortunately the CL held it's own over-nite...The same 5ppm yesterday was the same 5ppm this AM...Sun is on the pool now, so I'll see how much I lose through the course of the day...Water never "tinted" green after the Clorine addition, so maybe I'll be OK.....Rain DID raise the PH to 7.8 though...

as for the specs:
18 ft round/ sand/ vinyl/ 7600 gallons
FC: 5
CC: 0
TC: 5
PH: 7.8 (acid added minutes ago)
ALK: 90-95
CYA: 30-35
CAL; 130

taking your cue, It's just ONE THING at a time for me !!....have not had the need to use additional metal out as the water appears to "clean-up" on its own after clorine additions...... However. my days of 'hard" shocking may be at an end...anytime more than 2 qt. of bleach is added, the water tints green....(In the past, I never thought twice about dumping 2 gallons at a time to "clear" things up).

So far, so good.....Thanks for asking....

Looks like your on the road to recovery.

Watch the PH bounce and do your best to keep it in check. 7.2 - 7.3. Your Alk level appears to be pretty good.

Something I learned from some other posts to help manage the PH is to lower your PH to the 7.0 with the MA and then Airate the water with a waterfountain or something to bring it back up.

**I used to have my water feature on all the time and could never figure out why my PH level kept rising....

Happy swimming.

Sounds really great I think you have it down pat now You can aerate the water by turning the return eye up so that the water bubbles on the surface of the water. Only do this if your ph goes below 7, cause your alkalinity is ok.

We only got about 5 minutes of heavy rain yesterday, although it looked like we were going have a really big storm
