Ooh… I love old school liverock, but with my current build I used old dry live rock from my yard that was brute cured for a few months. It worked great. My theory is the phosphate sync that it provides promotes phosphate stability in new tanks which is one of the most critical aspects in a Reef tank. I just added some dry barren mined base rock to my frag system and it immediately bottomed out my phosphates making my corals very mad. I’m here to agree with you that live rocks is good, But promote my idea that old live rock is really good too if you want to avoid the hitchhikers and still have success. Dry base rock is very hard to start a tank with. You’re going to battle the base rock binding all the phosphate and then once it reaches equilibrium cut back on the algae wafers (what I’m currently adding to my frag tank to try and increase phosphates).I will never start a tank without Live Rock for the win.

), and it got me thinking... What are your reefing "non-negotiables"... Those few things that you believe to your core, and you will never compromise on. For example:
