I am now maintaining my own pool;I was relying on pool professionals. I have a 24500 gallon gunite pool. In May the pool was opened, it remained green and I had to have the inside grid of my DE filter replaced. I have been balancing the chemistry on my own since July, usng the test kit and bleach. The water has remained clear. My questions are as follows:
1. The chemistry is Free CL 9.5 CL 0.5 Total chl 10
TA 140
CH 250
pH8.2
CYA 100
CYA was even higher and I took some water out and replaced some water. I use the pool caluculator and keep the chl on the higher side. Is there any thing else that I should do in terms of the chemistry?
2. How often should I backwash the DE filter? When they replaced the grid manifold, I was told by some else that the pressure reading was not set correctly. It reads 30 and has been since they did their repairs in May. Should I just backwash every week? Now when I back wash, how much of the the DE do I replace? I was told that I would put the DE straight into the skimmer while the filter is flitering the pool. Is this correct?
Thanks,
DF
