I am buying a foreclosure house. The pool pump hasn't run in over a year, and is very green (Central Florida).
I have read a lot on this website and most people seem to recommend fixing the existing green pool water, but it seems like it would be faster and easier to just drain it, clean it, and refill it.
It seems to me that a drain/refill would be better in many ways. 1) Quicker time to sparkling pool. 2) Probably less chemicals as I don't need to kill a 3/4" thick matt of algae 3) No clogging up the DE filter 4) a lot less backwashing, and therefore less lost DE powder too.....
The only downside is where to get the water. The house is on a well and septic. The toilets and showers are orange, so I know the well water has high iron.
But the house is on a small lake!
Granted the lake is kind of a swamp too, but at least I could try to draw from the middle of the water column and I could filter it too, so at least whatever algae I got in there would be small and suspended in the water column and not hundreds of pounds of it. The real advantages of the lake water are: low iron, less organics than the green pool, and it's free water.
Please let's discuss the pros and cons of doing this.
