Think I have this solved. I found high nitrates in there.
But...first I would think that if breeding resumed, then that would mean
I had actually found what was wrong.
So this is guess work I suppose but how long after the nitrates are down
to a reasonable amount would be your guess as to when they may start
back to breeding ?

Sorry, just plain RCS...nothing special.

Sustained high nitrates can cause fish to go sterile. Not sure if it has the same effect on inverts. Sounds like you to need to work on your water change schedule.

I would give it month to adjust, and keep up on water changes. they help to spark breeding
