Hi all and thanks for the opportunity to post my questions!
I started my shock process about two days ago using liquid bleach an have monitored pretty closely however I will admit it was not hourly.
I can say confidentially that I have kept over 10ppm of cl2 for the duration as the hach test kit I'm using neutralizes 10ppm per each drop of thiosulfate and I am clearly over 10ppm but under 20 ppm, as a second drop of thiosulfate renders the sample clear in color, until me K2006 kit arrives.
My levels are as follows
Greater that 10ppm which conforms with the pool calculator qtys required, although I realize my shock levels are to be 16ppm with a level of 40cya
CL = 10 ppm plus
CYA = 40
PH =7.2-7.4
TA = 100
CH = 625 (really high I know)
Overall my problems that I just cannot seem to get all the algae,it is light in color and constant brushing makes the algae easy to see as the light green film brushing churns up.
Filters were cleaned just before I began the shock process and some foe the bands are broken, overall the 4 filters clean up pretty good.
Pool is a natural rock pool with multiple boulders under the waterline and I have never really been able to keep the pool consistent.
Water is only one year old and pool is 6 years old.
Thoughts/suggestions?
1-more vigilant on cl2 levels, keeping them in the 16-20PPM range.
2-CH levels a concern or having an impact on algae control measures?
Thanks.
