Something like Tetra Tabimin might work, it falls into dust-like bits.
Congrats on the berries
The easiest way to raise KH is by adding crushed coral in your filter media. I'm not familiar with the innards of your cannister, but I assume you can trade out some media for either crushed or broken coral pieces, right?
That'll help the shrimp shells.

You water sounds ok
Good luck, Wes, sounds like all your aquatic pets are happy right now, don't rock the boat!According to the one site I am right on track at 7 degrees KH. I guess if it ain't broke don't fix it applies here.
Best wishes,
Wes
