How much Live Rock?

[tinyfish]

I could not find this in the sticky notes. Is it one pound per gallon?

And does the size of the rock matter? In other words does a bunch of small rubble that weighs the same as one big rock provide the same amount of benefits?

It's surface area of the rock that makes the biggest difference.

Smaller rubble is harder to build structures with, but normally has more surface area.

also buy quality live rock. It should feel light plus have a lot of crevices, holes ect in it. For eg Figi rock.
These holes and crevices are need to support the anoxic bacteria--the bacteria that act on nitrates and reduce them to nitrogen gas completing the nitrogen cycle.

All that math is BS. Go slow. Maybe one rock at a time. See how it works. Turn it, turn it , sweet!

It is a puzzle.

if its for your 20 gallon long id suggest 15-20 pounds to start, see how it looks, if your not happy with the layout add a bit more etc, once the system is thriving and full of corals and fish you could always add a little bit more when and if you need it, but do it very slowly and in small amounts

Depends on what you plan on doing with the tank. If you want to keep fish like a powder blue tang, you need lots to let them graze constantly, if you have multiple fish it is better to have more to give lots of hiding places, what kind of filtration also plays a factor, it really is an open ended question. First you need to decide what you want to keep and what filtration you wil be running and take it from there
