Live rock Per gallon

[daniella3d]

It's not just about adding pounds of liverock to an aquarium, it's more about the type of liverock that you will use.

If you put 100lbs of dense heavy and non porous liverock in your aquarium, it's not going to be as efficient as 30 lbs of lets say nice porous Totoka liverock. I have zero nitrates in my aquarium and I have about 45lbs of liverock Totoka in my 70 gallons tank. It does the job very well because it's so porous so deep inside it also denitrify.

So it is best to have porous liverock that weight not much vs heavy dense stuff and the weight you will need really depends on that.

Never mind the small rocks in the middle just keeping them alive for friends sump (when its done)

^agreed.

the quality of the live rock over the quantity is something that should be heavily emphasized by all people imo. in terms of biological filtration, surface area is what it's all about. selecting light and porous rock over heavy and dense rock will not only be easier on your wallet, but will be a more efficient means of breaking down your nitrogenous wastes.

I didnt even think about how porus it is, I have some very nice porus live rock and a few other pieces that are super dense (almost like regular rock) I didnt really think that the porus stuff is what I want till you brought it up, I think I have all Fiji live rock but as I bought it from a local reefer I really dont know as she was just selling it cause her husband took off lol

Yeah that doesn't look like 50lbs so I would look elsewhere for better rock. The rule of thumb is just a guideline and few people actually use it these days.

For example I just put 75lbs in my 100 gallon display which has a total volume of around 160 gallons, I won't be adding anymore rock.

Waw that photo is absolutely outstanding. I appreciate the thread. I've been thinking a lot about what it is I want to add and how much-to my new tank. Great thread.

I started with about 60 pounds of liverock and added another 90 pounds of dry rock to my 180 gallon tank.

No issues and the fish have lots of room to swim.

I don't think you got 50lbs of live rock, did you actually see the weight on a scale? I got 60lbs of live rock for my 90g and had to put some in my sump as it wouldn't all fit in the tank. Take a look at people's tank photos and see what style you like. Some like their tanks open, some like lots of shelves and arches and some like a big dense wall of rock against the back of their tank. If you have good porus rock the lb per gallon rule of thumb isn't a must by any stretch. What's important is that you like the look of the tank because if you don't why have it? You can also get creative and use clear acrylic rods and black zip ties to design your rock work.
