I am so pleased to have found this site and I am going to say a big "THANK YOU" in advance for all the great advice I know we will get from everyone on this forum. So...here goes...
We took over from our pool service about a month ago. I have been reading up on BBB and trying to get educated. I began testing the water with the suggested kit from Walmart (because of cost and accessibility) and we have been adding liquid chlorine as well as vacuuming/brushing/netting out the gunk. We live in Palmdale, California, which is the high desert. The water in the pool LOOKS fantastic, crystal clear. The tile and plaster, not so great. The previous owners let it go and the pool guy we hired on when we moved in 2 1/2 years ago gave us the history of draining and dealing with it prior to its sale to us. It was black and nasty.
Here are the current specs. I did the chemistry test today with a TF-100 kit we just purchased.
15,500 gal. Nautilus NS36 DE filter, IG, plaster, 1.5 HP pump
PH= 8.2 +
FC = 4
These results are completely consistent with what I was getting using the Walmart kit, so I am fairly confident they are accurate. I had to dilute the water for the CYA test and this is the third time I've done it. The ph is just bright red, off the charts, so I really don't know what it is.
By all accounts it seems as though we will need replace around 75-80% of our water in order to get it balanced. Am I wrong to be a little bit annoyed that the pool guy would allow the water to be so out of whack? Anyway, here are my questions.
1. HOW do we drain the water out of the pool? (Perhaps a stupid question, but we honestly don't know!)
2. Will it be pretty straight forward how to balance it once we refill?
3. Are there things we should have done since we need to remove so much water? (our light is out, for instance, so probably a good time to replace the bulb?)
I have included few photos of our equipment.
Thanks for taking the time to help us!
