Pool was crystal clear through most of July.

It rained and then it started to get cloudy/green… we added a bag of shock that night and ran the filter. The next day it didn’t look any better or worse.

+ We went to the store and they sold us Green to Clean. We used Green to Clean and Power Powder Plus. The next day it was a little lighter green.

+ We shocked again and it was a pleasant blue green in time for the party… but not crystal clear blue like we wanted. The result was also that the alkalinity and chlorine were REALLY low – my Ph was a little low too. And the pool was getting greener.

+ Soda Ash was added to increase Ph.. it brought up the TA to around 120 but the Ph stayed around 7.2.

+ We added Imperial Black Out Algaecide

+ and Green Out Shock in a moment of panic. The next day the Ph was up, the Chlorine was way up (around 15-18ppm). The pool was still green. That night the chlorine was down a bit (I don’t remember the number – but I added more shock).

+ The pool guy said it might be metal. We added Metal Free. No change.

+ The following days we would bring the chlorine up to 18 or so.. if it dropped below 10ppm. The green stayed.

+ Pool store said we didn’t need shock.. it was probably a faulty filter and gave us Blue Seal product.. a cationic polymeric coagulant? He said It would help filter out the particles that were making the pool greenish.

+ A few days later the green just got REALLY bad. That’s when we started adding bleach. I added 1 gallon the first night and it came up from 12 to around 18ppm.

+ I started testing 3 times a day, keeping the chlorine levels upwards of 15 (usually closer to 20).

+ All I’ve added since the 5th has been straight 6% plain bleach.

+ I went to the pool store today and he did a manual test on the water. He said all my numbers are pretty perfect except that my chlorine is astronomical. I have no metals in the water. He was / is stumped.

I am frustrated.. and now I don’t have a way to test my CC and FC until my new reagent comes.
ALSO.. no slime, not slick or anything. You wouldn’t even know it’s green if you just jumped in.. the water feels great.
