Joe, the following Crypts not only tolerate alkaline water, they'll thrive in it.

usteriana
aponogetifolia
affinis
hudoroi
bullosa
undulata

I'm sure there are others that I'm missing.

Hi - this thread is a pretty good read on the subject.

The "final" list from that thread:

C. affinis
C. aponogetifolia
C. auriculata
C. beckettii
C. bullosa (special case, more information needed)
C. ciliata
C. cordata (unsure if the different varieties will)
C. crispatula (unsure on varieties, balansae does)
C. keei (special case, more information needed)
C. parva
C. pontederiifolia
C. spiralis
C. striolata
C. undulata
C. usteriana
C. walkerii
C. wendtii (all varieties to my limited knowledge)
C. willisi x "lucens"
C. willisi

(I've been trying to stick pretty close to this list while collecting crypts )
