Best Base Rock?

[Myka]

So I'm looking at different sources for dry base rock. Part of it is because at this point in my life I cannot justify spending $500 on live rock, and partly because I like building/making things. So I'm gonna cook some dry base rock in a dark bin at the highest temperature my heater will go (to leach the phosphates out of the dry rock) and feed it bacteria, vodka, and ammonia for a few months and see what happens. I've read it works quite well for getting good levels of aerobic and anaerobic bacterias. I'm interested in an "experiment" sort of way. Gives me something to do over the winter. LOL!

So, what should I buy? So far, I think the Caribsea Lace Rock looks pretty good. Has anyone bought a box of this before? What kind of sizes and shapes should I expect? Are there better dry rocks out there? I'm looking for nice shapes (not bricks and boulders!) for a 65 gallon tank, so I would prefer to have several in the 10-14" range, and then the rest in the 6-10" range.

Comments? Ideas?
