Thanks,Guys! I checked out Shineks site. Crap! I was supposed to take out the big stuff before I added the sugar sized stuff! Do you think it will just move up, where I can get it? Or should I stir it up? I could be patient and wait and see......! Does anybody know anything about these "recharge" kits? Has anybody ordered one ? I'm thinking maybe we can get together and trade some sand.....And thanks for the caulerpa offer! I just can't get it to grow. I had a sump full in our last tank, but this tank it just won't grow. I added new lights, and I know there is nutrients, 'cause we've got algae in the main tank.Can't figure out what's missing. Thanks, again!!
