My lilies do great, too. But they're in dirt.

I also use baking soda but I'm curious since I read so much that says
the plants like it neutral (and everything also says the fish like it
above 8). I'd think plants in dirt wouldn't care as much but plants in
pea gravel would. Unfortunately it's starting to get a bit late in the
season to experiment.

Don't know about plaster of paris. To me, the baking
soda is cheap and effective.
