Live rock

[Myka]

I look for porosity as well. Pick the rocks up...they should be kinda light for their size. Less porous rocks will be really heavy. I look for good shapes as well. Stay away from the brick shape!! Go for long and skinny or plate-like, which are my preferences. Personally I don't like a lot of bio-diversity on the rocks as I find most of that diversity tends to be algaes! I really like to put my fresh live rock into bins and "cook" it in the dark with a powerhead and a heater, doing weekly 100% waterchanges until the phosphates read 0 (this may take 12 weeks or more). I will never again set up a tank without cooking the LR.
