Thanks guys. I don't plan on any macro/plants in the display tank just LR and easy to keep corals, anemones and such. I really like the look of sand on the bottom of the display tank but I thought it had to be LIVE sand? You can use sand from home depot? In the main tank I want about a 2inch layer. And for the live rock I was thinking around 100lbs. How much base rock could I get away with? What's the minimum rock I could start with to get the tank started and cycled? You guys rock!!! :mrgreen:
