Howdy. Two days before Memorial Day Weekend, I drained the pool completely. Kids had painted it two years earlier and did a terrible job at it... two different shades of blue, incomplete brush strokes, etc... Really didn't live up to its potential. During Saturday of Memorial Day Weekend, I painted it and by 1PM, began filling it. By Memorial Day, it was about 85% filled. We have water authority supplied water, so there was never a doubt as to what was in my (now) 15,000 gallons of water.
At that point I added 6 pounds of Calcium Hypochlorite. The theory went "Well, I've gotta chlorinate it somehow, and with the Minimum 70% Available Chlorine written on the bag, it sure seems like a good deal." PH was then out of whack, but I managed before the end of that week to get everything under control and have maintained to do so since.
Also it seems that I have grown to despise CYA the more I read about it... Even though THERE IS NO CYA in my case! I know I'm not alone in this thought process. I mean, if you can't (easily) get rid of it and it could only come back to bite you, then why add it?
Daily maintenance is about 8oz. of Calcium Hypochlorite... dissolved in about 3 gallons of warm water. Generaly speaking, the FC is about 1-3 in the evening when I take readings. It seems to hold overnight - it's only the UV rays that seem to consume it.
I am willing to continue this way for the next two months. It is truly a labor of love... and I'm up to the task.
PS: After 4 weeks, the pool is still crystal clear. I will this weekend drop a quarter into the deep end and attempt to see if it's heads or tails
