Hey everyone! Thx for the all wonderful feedback. Sorry I haven't been online in 2 days...I was dealing with HUGE swamp in my backyard. In short, I came last week from vacation after 2 weeks to find my pool completely taken over by green algae. The silver lining in it though lead me to start maintaining it myself and to TFP!

To answer few of your questions: The pool & spa are somewhere between 85k-100k gallons, I bought the house with the pool already built so I am not sure on exact size...I have an original layout design from previous owner and kinda narrowed it down to 90kish. It is 88'L x 40'W (shallow area) x 18'W (grotto area) x 22'W (deep/slide area). It ranges from 3'D to 8'D gradually. The spa is probably about 18'L x 10'W x 5'D. The tall stepped fall is 15'H above grade, the spa itself is 5' above grade.
