I was just informed one of the high schools I supply fish, feed, and a recirculating system to has installed a water softener. I'm guessing Ph will have to be monitored and something added to bolster alkalinity?

The fish species will be tilapia, bluegill, or yellow perch, or all of the above.

Aragonite or oyster shell grit in the filter may fix that.

I thought about that. It would have to put into the moving bed filter (biofilter). Not sure how that would work. The mechanical filter gets scoured out weekly with a garden hose on high pressure.

What about filter bags with oyster shelling hanging in the fish tank (150 gallons circular tank)?

You could try adding limestone too. I used it as a pH buffer with good success when I had a blackwater setup and was filtering through peat moss. It will leach CaCO2 into the water.
