As someone mentioned in another thread, the kit manufacturers
generally have enough meta to get you through to bottling. If
you rack a couple of times and don't have the equipment to
measure the levels, then you can add 1/4 tsp after the second
rack or prior to bottling in 3 or 6 months. You probably have
more then enough SO2 to start bulk aging.

Maybe, rack in 3 months and add 1/8 tsp, wait 3 months and bottle
after adding another 1/8.
