Thanks in advance for your help with this one! I have a PebbleTec pool that did not have any circulation (pump was sucking air after leaf canister broke apart) and also did not have any chlorine for 10 full days. I am in Arizona and it is around 104 degrees here (water temp approx 80). It has now been almost 20 days since the pool turned green.
Before I found this website, I tried my own fixes.....
Dumped in 3 bags of shock (dicholor). Wait one day. Dump in one more. Wait a few days. Dump in one more.......give up and go to pool store.
Second...(yesterday at 3pm)
Went to Leslie's pool store and bought Black Algae Destroyer. Used 1 1/2 - 2 times suggested dose. Waited a day....no change. $35 wasted.
Now I find this website and do LOTS of reading and am trying the following (WILL THIS WORK?!?!?!?!?)
Readings yesterday from pool store....
FC = 6.7 (I maintained 6.0 - 9.0 FC for the last 3 days -- thought that was enough...was wrong)
CYA = 100 (I tried testing this and got a MUCH higher number, but as other posts suggest the test isn't accurate w/ green water)
TDS=2500 (AZ has very hard tap water)
Today I bought 9 bottles of 6% bleach (182 oz. size).
Today FC was at 4.5, so I added 4 bottles (pool size is 14,000 gallons). Did this at 5:30 PM. FC at that time = 30
Re-tested at 7:30 PM (2 hours after bleach)....FC still is 30
I have read that this should be going down and to watch it closely. Is it possible that by holding the FC 6.0 - 9.0 for 3 days has been helping?
Please keep in mind that my CYA may be very high.
I am concerned about bleaching the PebbleTec and/or ruining the pool equip. so I figured I can start with FC=30 and see if it works. If no improvement in 2 days, then go to FC =50???? Is that even safe?
Wow, I sure got a strange look when I bought 9 huge bottles of bleach....I hope this stuff works!
Thanks in advance!!!
