well, didn't have enough $$, so I ended up making water took a long time. Fish are in the garage of the new house, and 210 is full, and salinity is almost correct.
I have a number of bags of sand that I just couldn't fit in the new garage setup, so I sun dried it for about 2 weeks, then put it in the 210, then after a week I was dumbfounded when copepods were flourishing in the new setup. Thought that sundrying it would kill off everything.
