Question High KH, Low GH from water softener

My KH is 20 dKH and my GH is very low (don't remember the figure now).

This is due to the water softener we have which replaces the calcium with sodium..

I have seen some people say that elevated sodium levels can be bad for planted tanks, but how can I measure my sodium level?

What can I do to make sure my water is going to be good for plants?

I saw this product called Equilibrium (http://www.seachem.com/products/prod...quilbrium.html that will raise the GH.

Does anyone else here use water from a water softener in their planted tank?

Any advice, anecdotal or otherwise is appreciated.

I recently moved into a house with a whole-house salt-based softener and it just about killed every plant in the tank. I'd never had such a system and I didn't know how they worked. It took me a while to figure out that the external faucets are not on the softener, so you might try yours and see. I installed an RO filter to deal with the unsoftened water. I'm still futzing with the mix between RO and unsoftened faucet to get the best results.
