Hi folks, first full year at the new home with a pool. We opened the pool in late may with no problems, balanced it fairly quickly and we were in balance for a while. I have a chlorine tab in each of my two skimmers. The pool sit in the sun the entire day, and temp has been 85-90 for over a week now. And now that the warm weather has it, it seems we cannot hold our chlorine levels. I also noticed in the past few days a red slime (bacteria?) starting to show up in the corners. So I put in 2 lbs of 'super-shock' Thurs evening.
We had our water tested at a chain pool store yesterday then today again. 0 FC/0TC yesterday. I then added what they suggested of 4 more lbs of the super-shock. I went back today and only .5FC/.5TC remain. They then tested for nitrates, and result was 10. They said I must drain my pool 1 foot, and then add 25lbs of granular chlorine because of the high level of nitrates. I lost confidence in them when she said "nitrates are a mystery". is that really the solution? and what can I do about the red 'slime' ?
here are my numbers....
FC= .5
TC= .5
PH= 7.6
TA=50
CH= 150
CYA=40
thanks!
