Swapping over from a 14g to a 35g so I'll need more sand and rock. The rock I have covered with a couple cerameco fixtures. The sand I'm not so sure about. I have some crushed coral, but not sure if I should use that, or buy another bag of live sand, or (and what I would like) can I get some cheap sand somewhere to put under the lives and I will be moving over from my 14g.
