Water all upside down after Winter - chasing Algae

[txcanes]

Test Kit - TF-100
Free Cl - 55 ppm
CYA - well over 100 halfway to the 100 mark on the test tube for TF-100
CC's - 0
TA - 100 - turned blue then yellow instead of red
Calcium - 0
PH - test skewed probably because of Total CL so high - low - 6.8 per drop test - did not have time to dilute test yet.

Suggestions welcome!!

FC is 55? That's very high, but it should kill any algae.
pH is super-low. Usually when FC is high, pH reads high. I'd add borax till you hit at least 7.0 for pH, and stop there till the FC comes down to the 8-15 range.

1. Dilute your pool water 1:2 with distilled water from Walmart (1 parts pool, 2 parts distilled) and retest pH. If it's still below 6.8, you need tor raise it ASAP. Borax, like Carl suggested, will work. But, if the pH is really low, soda ash (Walmart "washing soda") or pH UP is possibly a better choice.

2. Have you been using trichlor or dichlor to chlorinate? (Like Carl, I'm wondering how you got FC=55 and low pH.)

3. How long has the chlorine been high? If it's been more than a week, and you truly have FC=55 . . . then your CYA must be extraordinarily high. Test the 1:2 dilution for stabilizer, and multiply the result x3.

Walmart has washing soda, too? I only know about Arm&Hammer (in the YELLOW, not orange, box).

Good stuff! I think "OxyClean" is mostly this and maybe Borax.
