I am so happy to have found this site! We moved back into our home the first of August after renting it out for several years. Within a week, we had algae developing and shocked per pool store instructions to no avail - had to leave for a couple of days knowing it was probably getting worse all along and it was!
After several attempts with other products, I found your site! It is working - the very bad mountain dew swamp is now blue but quite cloudy. I started the process on Sunday and have a couple of questions though. I did order a Taylor K2006 but it is not here yet, so I am working with the test strips and data from the pool store on Sunday.
Values Sunday (Pool store):
PH - 7.4
TA - 90
CH - 180
CYA - 20
Now (approx) with test strip:
TC - >10
FC - Close to 10 (the purple matches the 10 more than the 20)
PH - 7.2
TA - 80-100
CYA - Low
I used the pool calculator for the "first" shock & pretty much think it is the yellow algae. Am I following correctly that the shock value should be about 14? How can I best guesstimate on the amount of bleach until the Test Kit comes? There were yellow patches on the steps this morning that were not there all day yesterday. Do I need to increase CYA - I bought some this afternoon but haven't put it in?
Thanks so much for all of the information! We are looking forward to using this method - so much to read & learn!
