Chemgeek,
Checked chlorine demand yesterday. took 2 gallons of pool water, added 3/4 teaspoon of 6% bleach, no fc. then in afresh sample added in a teaspoon - blaze of red. So went down to 7/8 of a teaspoon and still got the same reaction.
so using pool calc got 20 gallons of 6% bleach and added in last night. ran the test again this morning.no measurable FC. diluted the sample with half pool water and half tap water still nothing. using Taylor K-2005. It is a DPD test, though not a powder. it is a liquid. stumped .

Referred to the pool calculator and it produced a 1992 oz of 6% chlorine to get chlorine upto 30ppm. Got 12 jugs of chlorox and poured them all in last night. Used Taylor test kit to check for FC which is still 0. Pool is clear with no visible algae

chemgeek,
Wish I had come to this forum before trying the metal treatment. We did have the exact issue of algae growth you warned about. However, we do not have algae growth at present. I also did a test dilution of the pool and got the CYA down to 80.
The main problem I want to solve is chlorine levels, which are stuck at 0.5 levels. If CYA levels are holding that back, and they degrade over winter, then do I wait for opening and then bring the chlorine level up or do I need to fix the chlorine level now.

Guys, Any thoughts...

We do winterize our pool. use a local service company. Usually get it done just before leaves start falling. Should be relatively soon. The pool company specs for interior of the pool call it a plaster. Definitely not fiberglass or vinyl.

I understand that now. What are my options - if any.

It was pool brand , active ingredients are Sodium Dichloro-s-Traizinetrione hydrated -99%, Available chlorine 55%

for removing stains, we were asked to use Stain Remover and Metal Free. Also a couple of weeks ago, we were asked to put in stablilzer. Pool is clear, no signs of algae

I used shock to increase the chlorine content. We buy ours from Sams club. I normally drop in a 3 pounds for a 32000 gallon pool. over the last weeks, we must have added in approx 25lbs over 2.5 weeks. Max at any one time was 7 pounds
We also used liquid chlorine last week and put in 3 gallons. We just got Taylor test kit and rechecked. FC was 0, TC was between 1 and 2, and CYA seemed to be 80
Let me know any other information needed

All,
New member and would appreciate any help. A few weeks ago, we thought we had metal stains and tried to get them out. using local pool store advise, we let chlorine drop to zero and used the metal free etc with associated backwashing etc. Since then we have not been able to get the chlorine levels back up. We have dumped in whole lot of Chlorine over this time, raised the PH which had dropped etc. The current readings are
Free Available Chlorine -0, Total Available Chlorine - 0, pH - 7.4, Total Alkanity 120, cyanuric acid 100, calcium hardness - 140, phosphate - 0, nitrates 5 ppm. A week ago, TC was 2, FC was 0.5 and we had 6.8pH. We live in North East and are running out of ideas. Inground 32000 gallon pool. Pool is clear and looks swimmable. Brown stains still there.....
