Every time I try to frag my Hawkins, the frags RTN from the base overnight. I've tried keeping the frags in the DT, moving them to the frag tank, dipping/not dipping, but I always get the same end result. I've tried cutting small frags and large frags and even placement under the same exact lighting/flow by wedging the frags into the rock beside the colony. Anyone have any pointers to help prevent future losses? oh:
