I'm new to this form and just completed my first round of tests with the new test kit. Here are the results;
TA 200 ( has been this high all year so far)
CYA I put about 1/2' of water in the measuring tube and the dot disappeared?! To low for reading?
Water temp about 87.
Here is the quick back story; I put the pool in five years ago and had no trouble for 5 years, i have had some serious medical issues and last year I did not keep it up correctly. Last August got what I believe was a case of pink mold, went to the pool store a bunch of times, added a bunch of chemicals as they advised and couldn't seem to completely beat it, closed the pool a week early, changed out the sand in the filter this year before the season started.
Developed what appears to be a case of mustard algae, white looking powdery substance, not slimy and not sand, when you touch it turns into a cloud. Every time I spotted it, vacuum to waste and added chemicals, brushed as per pool store instructions. Cleaned and shocked the pool, ran the filter on recirculate for a few days and it grew back indicating that it's something organic (I think). Every time I see it I vacuum to waste and I have been doing a lot of shocking, I don't know what I'm doing and it appears the pools store folks don't either, since I have not been able to beat it, ready for a new era the trouble free pool way, read up on mustard algae, seems like I need to follow the instructions for 5 days of SLAM then one extra day of super slam, I'm just not sure if I need to do anything else first like correct the TA or CYA, any help would be greatly appreciated!!!!!!
