Thanks for the info. What is the best to use?

Hello all. I have a 33' above ground pool that is full of algae. I was told to drain it because it would be cheaper and faster than shock. I did all but about the last 5 to 6 inches. Then I was told I shouldn't have drained it, but just shocked the mess out of it. Too late. I got most of the floating algae out but there is some still on the bottom, along with 5 to 6 inches of water. Would it be ok to start filling it up with water since I got most algae out? Help! This is my first pool, and such a mess thus far. Also, I was told that I shouldn't have drained it b/c the sun will shrink the liner without the water in it. I'm trying to clean and de-algae as quickly as possible. Any suggestions, recommendations, advice is greatly appreciated!
