Hi, Summer,

based on the dimensions above, that DOES come out to about 12,000 gallons. Let's use that for now...we can tell later if it's incorrect.

I'm going to offer a path you can take if you choose. It will address your algae problem but may cause your staining to worsen. I've reread some info on metal and Marie seems to think that the staining can be overcome at any point so, if it were my pool, I;d give this a try. That said, keep in mind that you're still gonna struggle with what we think is iron in your water....even after you get your pool clear.

1. Don't put anything else in the water unless we talk about it here...it'll cause you further issues perhaps and certainly cost you money you don't need to spend. Don't even use the products you've bought...that'll come later. Then, download mwsmith2's calculator from any of his posts and use it for all your calcs.....plan on 12,000 gal for your pool size.

2. Put in one quart of muriatic acid (into the jets, pump running) as soon as you can get it. Test your pH and post it back. Hopefully, it'll be about 7.2-7.4.

3. Get about 15 gallons or so of 6% Clorox and have it on hand. Your gonna use most of it right away. be ready to get some more very quickly.

4. You need to test for CYA and tell us what it is. If you can't test for it with your kit, please get one that does.

5. I'm gonna' assume you can get all above done by tomorrow evening (the CYA test is optional at this point, but don't put it off too long)

6. Tomorrow evening, after the sun is very low in the sky, put in 4 gallons of the 6% bleach. That should raise your Cl to 20pp, (but it's gonna start dropping right away) Find a way to test for CYA and post that info as soon as you can. You'll need to get some in there the next evening.

7. The next evening, test your water again for Cl and pH. Adjust your pH with either muriatic acid (down) or Borax (up) using the calculator. Now add enough Clorox (into the skimmer, pump running) to bring your Cl back up to 20ppm.

8. Hopefully, you'll have gotten the CYA test done, and purchased enough (if you even need it) to bring your CYA up to about 40.

Let's stop there for now. More steps at this point would be information overload. If you can do the above, asking any questions along the way, everyone here will help you get your water sparkling.!
