Newbie needs help. Need a Plan Of Attack To Get This Pool Open

[NullQwerty]

Hey...I'm Sorry...My terminology may be off...adjust for the newbie factor . What I meant was that during the winterizing process, the filter was opened up and cleaned. I called it Grids, but it may be fingers. Also I thought it was called backwashing what I'm doing, but maybe I'm wrong. When I say backwash, I mean I push the handle at the top down slowly and then up quickly 6-8 times which removes the DE (the filter manual calls that process 'bumping'). Then I open the drain valve and let the water and DE drain out. I then turn on the pump to further clean it and get the gunck out. I then close the drain valve, start her back up, and then add more DE.

The size of my pool is about 36 feet by about 18 feet.

My readings from the other day are here. Again, no chemicals have been added since this was taken:
Saturation Index: -0.7
TDS: 500
CYA: 70
Tot Chlorine: 0.3
Free Chlorine: 0.3
pH: 8.2
Demand Drops: 2
Total Alkalinity: 36
Adj. Total Alk.: 15
Total Hardness: 82

What do you guys think? Anything I can safely do without turning on the pump?

Thanks guys!

Waste: My problem with vacuuming to waste is that I don't have a waste line, so where do I put all the outcoming water? I imagine it would kill my lawn, no?
