Okay, as previously discovered in my beginner thread (First test results are a little worrisome), I have high CYA and iron stains. Please help me, a beginner, formulate a plan to resolve both issues on my 2 days off in 10 days.
First, chemistry:
FC 10ppm (today)
Ph 7.2 (today)
CYA >178 (probably closer to 250 -- but who knows, I tried it at 50% dilution and it was over 200 on my test)
Further notes, my DeltaT is 3.45 (assuming Leslie measured pool tds of 1000ppm, city specified TDS of city water at 247ppm), my pool is 5.3K gallons.
The plan: Pull up the iron, replace the water, get into maintenance. Liquid chlorine and chill thru the rainy season.
1. I plan to buy this submersible pump (submersible pump)
2. I plan to buy this abscorbic acid (ascorbic acid)
3. Measure the rate I can fill the pool (the most likely bottleneck)
4. Pull out the cartridge filter
5. Spend 24 hrs treating with abscorbic acid (0.5 lbs to begin with, add more if stains still persist at 8 hrs)
6. I plan to sequester if you say I need it (the pink stuff)
7. After 24 hrs of abscorbic acid, begin the water change
8. Perform an in-place drain with a pump at the skimmer and a hose at the deep end (3hrs, approx 6k gallons I guess, so 20% more than pool volume)
9. In the worst case I'm sitting at CYA 30ppm I guess. Best case 0ppm CYA.
10. Immediately dose with 60 oz of 10% liquid chlorine, should get me to approx 4-5ppm FC.
11. Check chlorine daily for next 4-5 days, performing Ph fixups and chlorine fixups.
12. After 3 days, if CYA is low, dose to at least 30ppm and set FC at maintenance.
13. On the following weekend, perform overnight chlorine test to confirm that I am in decent maintenance.
14. Have a margarita.
Okay, what steps am I missing or over simplifying?
