Long story but I'll try to be concise.
Please forgive lack of BBB method; still using traditional pool chemicals (Trichlor, cal-hypo 73%) at this point.
Drained and filled my pool this spring.
Within a month of opening, my pool was permananently green with bubbles in returns.
Uneducated maintenance (HTH shock, inadequate shock levels for high CYA, test kits, etc.) led to race with algae that I never won for reasons listed below.
Through this period, I discovered:
- Cartridge filters were busted (blowing debris right back into pool); replaced.
- Pump seals/o-rings were shot; replaced.
- Jandy valve o-rings were leaking; replaced.
- Skimmer pipe was plugged; cleared.
- Main drain was clogged; cleared.
- Suction side vacuum was not walking well; haven't resolved yet.
- CYA was about 80; did partial water replacement to drop near 40.
- Shocking pool turned water GREENER. Country well water had metal in it; added Metal-Free.
After this effort, pool appears to be mechanically sound. Good flow, no air leaks.
Last weekend, (re)found this site and started proper shock treatment (albeit with 73% Cal-Hypo, instead of bleach). Over the course of 24 hours, maintained proper shock levels until pool went white, pump 24/7. Had to go out of town Tuesday-Thursday but managed to reach "no overnight FC drop" just before I left (testing, unfortunately, with HTH test using dilution to read high FC levels). Pool has never reached crystal clear but is now cloudy aqua-blue, can see shallow bottom (3-4') but not deep (10').
Received TF100 kit couple days ago. First TF test results:
Added PH-Plus to bring PH up to 7.2 (currently), stabilizer in amounts to raise CYA to 40 (haven't retested yet) and cal-hypo to drop CC (now 0.5). Added SuperFloc last night, no appreciable clearing or fallout. Also, re-tested overnight FC drop with close to, if not acceptable, results. (Didn't test morning until after 2 hours of sun, drop 1.5 ppm).
At this point, I'm inclined to restart shock treatment and see if pool will reach clear. Would you agree?
Thanks in advance!
