I bought this Bio Cube 29G complete with live rock and sand about 2 months ago. I've added some more rock since but think I might need more. Any guesses as to how much I currently have? Should I have 30lbs to follow the 1lb/G rule? Should I add cured rock or live rock?

id say your pretty much on par with 30lbs. i wouldnt add more. also, the 1lb per gallon rule is more stores selling rock. i have a 75 gallon and can tell you i only have 50-60lbs in it with it doing fantastic.

if that is 30Lbs, then i must have miscalculated my rocks. I must have over 40lbs in my tank.(29G biocube)

What lighting do you have there?

Well the rock that I bought that looks like dead sps in the middle weighed 6lbs, so my guess would be around 25lbs. I saw another biocube today and he had it packed all the way up to the back wall to the brim with rocks. I thought the rock is not supposed to touch the sides, but kindof want to add more so I have more coral real estate.

Not all live rock is created equally.

My guess is that 20-25 lbs of good Pukani will outperform 50-60 lbs of crappy base rock; easily. Very porous rock that displaces a large volume of water is the goal. It isn't fair to compare very dissimilar rock and pretend they are the same. They are not.

Sheer weight of rock may be all we have to refer to, but it is a poor yardstick.

Don't use rock weight as a gauge of how much LR you should have in your tank. Go by what you like the looks of.

If you need more rock to give more room for corals, then yes, you need more LR

If you think you need more LR for filtration reasons, there are other ways of dealing with that. But really, unless your tank is extremely minimalistic or equally overstocked, you won't have that problem.
