It's just a website I found and being new to this hobby I thought it looked realy neat.But then again as you know Krish I am new,and looking for my LS and LR to start.
Was thinking of Marco rocks for the base rock which will save me $,and I have 2 80 lbs of Carib Sea Aragonite now and need some finer sand to go with it for my DSB that I want.
