Hi,
Thank you all for your help in advance. I am in Chandler, AZ and have been learning a lot about my pool thanks to this forum. I obtained the Taylor 2006 kit and performed a test today with the following numbers:
PH 7.4
FC 5.5
CC 0
TA 70
CYA <30 (I could still see the black dot even when filled all the way to the top)
CH 850-1000 (I couldn't get an exact read since the color is between purple and blue in this range)
Salt 4490
My questions:
1) Should I drain the pool now to lower CH? What risks do I run maintaining a pool with such high CH? Will this affect the life of the SWG? My salt level is also high which would be improved by a drain.
2) Pool stores are getting different numbers on the CYA. I have run the test three times now with consistent results (sub 30) with my home kit. Should I go ahead and add some conditioner? With a CYA of less than 30 shouldn't the FC drop very quickly during the day? How can I be sure that I need more in the water since this can't be reversed once adding?
3) I have had roughly 10 black algae spots pop up over the last few weeks while I was maintaining FC around 1.5-2. Given this history of black algae, what level should I keep the FC at now and into the future?
4) I am currently treating the black algae by brushing with a stainless steel brush and rubbing a trichlor puck on the algae spot. Should I continue with this and keep my FC at a certain level, or initiate a SLAM process and stop with the trichlor puck?
Thanks!
