Hi,

I just started a salt tank, it's 41G fluval. I have 49Lbs LR that i purchased that was well established in another tank, plus 60 llbs of aragonite live. The rock and sand has been in the tank for only about 4 days and my readings are;
HG 1024, 79.8 degrees, Ph 8.2, amnonia 0, Nitrite 0 and Nitrate 0. I have the Marine Glo and Power Glo lights on a timer for 10 hours on 14 hours off.
I have noticed coral coloration on my newest rock that matches the other rock overnight, but have not seen any algae start to grow. It almost seems too perfect, am i being set up for disaster?
I have about 6 crabs and 8 snails right now in there. Should i just keep checking my readings daily and watching out for dying critters? I plan on waiting another month before i add any fish, but should i be concerned about the critters/janitors?

thanks!
