Owned house and pool since Aug 09. first pool. Have everything pretty much under control. [Thx to you people]
But I have decided to drain approx 50% and refill. According to the PS the TDS and phosphates are really really high. Also CYA is at 70+-, CH is @ 340.
Pool has looked great all year, and I have read the non problems TDS and phosphates really are, but I think it will be good to get a fresh start.
I have waited until the weather has cooled down and overcast. While I will drain and refill the same day, will I be chancing de-laminating any plaster from the pool?
