Will this work?

Several questions:

1. Have you seen any evidence of new staining?

2. Why is the cal hypo expensive? How are you buying it?

3. Do have access to a Sams Club? If so, buy their 24lb pack of 1# bags of 100% dichlor shock. Each bag will add about 2.5 ppm of chlorine, and about 2 ppm of stabilizer to your pool. Otherwise, order dichlor from Amazon:

Kem-Tek Dichlor 22 lbs

You need to start bringing your chlorine and stabilizer levels up. You can use the dichlor to raise both at the same time. I'd aim for 1 - 3 ppm levels. You can add the dichlor to your skimmer, but take the CuLator out before you do, and replace it after. I don't recommend buying dichlor locally, otherwise, at least until you are an EXPERT reader of chemical labels. The chlorinating pool chemicals sold at Walmart, Kmart, Costco, and most other local stores are diluted blends, sometimes with copper and other products with bad side-effects.

1. Yes, only on my stairs though. The liner seems to be clean to this point. I really hope it doesn't come back like last time. Literally stains 85% of my liner.
2. The Cal Hypo is sold at a local pool store and costs $50 for 12 bags. At this rate, I figure I'll be spending $100/month to keep chlorine in the pool.
3. No Sams club. Will most likely order Dichlor from Amazon.
For now I just have 10% liquid chlorine and was planning on using that until I get something else. Thanks.

Well, I'm convinced that I need to drain my pool and start over. The stains have come back. Not as bad as the first time, but enough to give my water a green tint again. My CuLator bag has been in for only 2 weeks and is now brown/tan in color. I'm guessing it did it's job based on the color change, but I cannot afford to drop $70 each month on a new one. I'm thinking of doing another AA treatment, then draining the thing once all the stains are sequestered. I'm just confused as to the source of the stains in the first place. I've never had to add fill water, and when we closed it last year it was clear, blue, and clean. The only thing I can think of is that there were 2 metal hook things left on each side of the pool that were used to attach a divider rope from shallow to deep end. I'm guessing the guys that closed the pool should have taken them off, but instead they were submerged from November until May. Anyway, I read somewhere that draining the entire pool is a bad idea because it could cause the liner to wrinkle. Any truth to that, or am I good to go if I decide to do it this year?

Draining a liner pool will almost certainly guarantee that you'll need to replace the liner. When there's no water to hold the liner down, it will float and will almost never stretch back out once it's refilled.

I'm going to ask Ben to pop back into this thread ........

Do NOT do this. As you've been warned, you can lose your liner. A stained liner still holds water. A ripped one, does not.

I'm just confused as to the source of the stains in the first place. I've never had to add fill water, and when we closed it last year it was clear, blue, and clean. The only thing I can think of is that there were 2 metal hook things left on each side of the pool that were used to attach a divider rope from shallow to deep end.

This is the 2nd reason not to drain. Until you know how the iron is getting into the pool, you have ZERO assurance that refilling won't make it worse.

My CuLator bag has been in for only 2 weeks and is now brown/tan in color. I'm guessing it did it's job based on the color change, but I cannot afford to drop $70 each month on a new one.

The fact that it's brown, doesn't mean it's consumed. If you got the $70 model, you got the 4 ppm model. In that case EITHER it's not used up yet OR you had an ENORMOUS amount of iron in the pool . . . OR you are STILL putting iron in your pool, somehow or other.

The only thing I can think of is that there were 2 metal hook things left on each side of the pool that were used to attach a divider rope from shallow to deep end.

Given that these are made of either plastic or brass . . . they are NOT the source of iron in your pool.

You may need to add another dose of HEDP. The CuLator unit cannot help with iron that's staining, since it's already insoluble. It can only work on dissolved iron. You might even need to use Vitamin C again.

But, simply draining and refilling, when the most likely source of the iron is your FILL water, makes no sense at all.

I realize that this is frustrating, but if you are going to solve this, you have to approach it methodically.

Ok. Thanks. Apparently something I did yesterday turned the water from clear to cloudy again. Used acid in a sock to clean the stairs, and swept. Back to square one with a green, stained, cloudy pool. At least I got one week of a normal looking pool. Haha. I will do the AA again when I get stocked back up with KemTek.
