Finished leveling, should've found a transit somewhere

So far i've got about 4 inches of water in the pool and it seems to be about 1 3/4" off level. Hope this isn't going to cause problems, maybe it'll settle some?
The fire dept in the city doesn't fill pools anymore so I'm held to my well which looks as if it will take about 4 days to get the 14500 gals I need. I also bought the 'aqua chem filter plus' from lowe's thinking it was sand and put in and wet 25# before I realized it, I haven't put in anymore. Any new info or thoughts on the 'filter plus' stuff? It's very course and in the morning I'll be going to get some sand.

I thought about using 75# of sand with 25# of the filter plus on top, any thoughts from anybody on this?
