How much rock do i need?
well i have a 150g tank, 72Lx18Wx24H. i want to have at least 3" in the bottom of the tank. i was thinking about goping by the "pound", but i think it may be eaiser to go to the lumbar yards and buy it from them. They sell it by the cubic yards. and all the calulations that i can come up with, i would need on 2.16 cubic feet. help me with my math if i am wrong.
Also what type of rock should i use, i want to go black sand, but that would cost me about $300 for it all.
and where is the best place to get the rock in bulk?
pics would be great so i can show the wife the ideas.
