Nobody knows! Help Is it phosphates, water to hard.......

[meme2]

ok, heres the results:
6.4 FC
.6 CC
7.4 PH
70 total alkalinity
CYA doesn't register
350ppm hardness
have had trouble most of the season keeping stabilizer up, but pool is beautiful, just spots on side and bottom.

Thank you!

OK, That doesn't completely make sense.

Did the R0013 + pool water remain clear? Or was it so cloudy that the CYA "didn't register"?

Clear ==> CYA < 20 ppm. // Super cloudy ==> CYA > 100 ppm

If the CYA test mix was super cloudy,

• mix 1/4 pool water with 3/4 tap water.
  (Use a shot glass, 1/8 cup measure, or even tablespoon measure.)
• Add 1 unit pool water and then 3 units of tap water to a glass & stir
• Retest mixture
• Multiply result x4 for actual CYA reading.

If it was clear, tell me whether you measure in the AM or PM, and whether it was sunny on the day you tested.

ok, if I did it right it was 55ppm. just a few minutes ago (this morning )with sun out.
The water was cloudy.

CYA = ~60 ppm

Algae chlorine dose = 25% of CYA, or 15 ppm!

Try keeping your chlorine between 10 ppm and 20 ppm for the next week. BRUSH the pool completely at least 2x, a couple of days apart.

You CAN swim: 30 minute pediatric "bleach baths" (Google for it if you like) are 50 - 100 ppm!

But do NOT wear new expensive 'fashion' swimsuits. Competition suits (Speedo, Tyr, Nike, etc) should be fine. Otherwise, wear older suits.

Good luck!
