Anyone have advice on were you can buy live rock for the best price. I'm starting a 29g Biocube this weekend and I am going with 40lbs of argonite and want to get at least 15-20 lbs of live rock to start my tank cycle. Also would anyone suggest mixing your own water or just buying it. $30 for premixed RO/DI water i think is worth the piece of mind but i am new so just looking for suggestions.
