Hi folks, new guy here. I made the mistake of buying a pool that's a bit too large. It's about 44,000 gallons. I don't know much about pools or chemistry, so I've basically let the pool store run rampant on me, with the usual financial casulties resulting. It's an "L" shape with a vinyl liner, a DE filter and a heat pump heater. I'm located on Long Island NY. I opened the pool yesterday and it's already crystal clear. I had my water tested today at Leslies, and it shows the following:

Free Chlorine: 0.5
Ph : 7.4
TA : 110
Calcium Hardness:170

That's all they tested for. They said I needed to buy Hardness Plus, to increase the water hardness, which I did. I added 27 pounds, as they suggested. In reading through the posts here, it seems that I don't need that for a vinyl pool, but then again some seem to suggest that I do because of my heater. The problems I usually have is that it's hard to determine what I need to add and when due to the size of my pool and my limited knowlege. Given the above numbers what do you folks suggest I add, and how much of it should I add? They didn't test for total chlorine or CYA. I have only used 3" pucks since the day I first got the pool. I had just a touch of algae last year for the first time. I loaded up the in line chlorinator today with the usual 3" pucks, so in time the chlorine will come up. Any and all input would be greatly appreciated. I know I have a HUGE learning curve ahead of me. Your input and patience are greatly appreciated.
Doug
