I have been using the BBB method for approximately two seasons and pretty much have a good idea of what needs to be done. My neigbors just got a new pool. It has a SWG but on the advise from the "pool professionals" at the pool store they were advised to add stain remover and metal remover (hard water remover) to the pool with the SWG off after the pool started to turn green. They were also adised not to run the SWG for 24hours... :?: :?: :?:
Late this afternoon I went to take a look at the pool and it had the signs of algae growth all over it. It was a nice blueish to greenish tint. We tested the water FC 0. PH 7.2 CYA 0. So, basically new water, nothing has been added but salt, approx. 2600PPM. The pool is 18700 gallons.
On my suggestion I had them add 4 jugs of 6% bleach to shock. I ran the pool calc and the results were the FC was raised to 13PPM. I know this is a high shock level. How long should it take for the chlorine to dissipate on a hot 90+ degree day and sun? I know they want to swim pretty soon.
