Like the rest of us schlubs, I'm new to the pool game. I have tried to do my research. Ill keep it short and sweet:
Problem- green algae spots formed sometime between Monday night and Tuesday evening on some horizontal flag stone surfaces ( mostly on shallow areas). Freaked out. Didn't want to get into this mess.
Situation- PO did a good job maintaining the pool uncovered through winter using chlorine pucks. Pool looked nice and clean and strip tested OK. We got insane busy moving in the last seven days and I forgot to check water quality for that week ( new habit I guess). Weather got warm/sunny quickly over the last four days. Water temp now at 76.
What I have done to this point-
Dumped in 5 gallons of 7.86% total available chlorine bleach. Brushed it in, etc. Added 400 pounds of salt. Have had pump running with robot running non-stop for the last week ( probably what prevented it from getting even worse/faster).
Today- brushed pool again and cleaned skimmers out. Appears that about half the algae disappeared overnight. But I did see two new single spots on a little deeper spot on the floor of the pool.
Got water professionally tested Wednesday( today) 9AM with these results:
Wednesday (today) 10AM-
Brushed again, added 3 gallons of same chlorine. Also added about 18 oz of Phosfree from Leslies. Pool has always been 99% free of debris and skimmers/pump filter are being washed out daily. Turned on SWCG and activated boost mode.
5PM- brushed pool again, cleaned skimmers. Nervous about adding even more chlorine.
Water still looks blue/pretty clear. Im still freaking out about the algae and hurting the pool. Water never went green nor did entire pool get covered in algae.
Two main pumps ( one for jets, one for waterfalls), twin sand filters, APURE 1400 SWCG, Gunite Pool, 35,000 gal, Kidney bean shape, with sun deck and stairs done in flagstone. Polaris 280. Think that covers it?
When looking at SLAMing, If I understand correctly I need to get my PH down first, then get my CYA up to 70? Then add the chlorine to get the shock level FC level going. But Im concerned about the PH and the CYA levels going too high or is that the risk we take? Do I need to SLAM really?
Leslies recommended a half gallon of algaecide tonight and said that should knock it out.
This is where I get lost. Any advice? Freakin out in Memphis!
