With a KH of 300 you don't need any of the baking soda. You put it in to
raise KH. The water softener salt works in a water softener to give an ion
exchange to remove the calcium and magnesium from the water on resin beads.
In the pond, it will not do anything but raise the salt level. Hard water
is not a problem, as far as I know for plants, and soft water is missing
some of the main minerals needed for plants and fish.

Have you fertilized the lilies? If so, when and how much? My hardy lilies
have smaller pads than the tropicals, and fewer blooms.

I admit, that I have never tested my water, before today. I haven't lost
any
fish, but my lilies only get 1 or 2 blooms and the leaves are quite small.
Could the plant problem be because of the alkalinity and PH?
My alkalinity(KH) reading was extremely high, 300ppm and my PH was over 8.
I read an earlier post about baking soda. Will this lower my alkalinity?
Also, I have very hard water. Should I soften it? Would water softener
salt
do the trick?
Thank you,
