How much LR do I have?

[OrangeKoi]

Does anyone have any idea how many pounds of Live Rock can comfortably fit into a five and a half gallon tank?

Well...going by the general suggestion of 1.5 to 2 lbs per gal, yata yata yata...

I would use more large rubble pieces, and about 7-9lbs

That's about what I figured I must have. 8 or nine lbs. Great. So I'll need double that amount in addition to what I've got for my 30 gallon cube eh?

Weight is tough though because some rock is very pourous and some is very dense. In my 75gal I only have about 90 lbs of rock but it seems like a ton of rock because I chose very "light" rock. If you choose a type of rock that is very dense you may need a considerable amount more. 1-2 lbs per gallon is what people suggest, and its a good rule of thumb. But it may vary greatly depending on what rock you choose.
