live rock as filter

[marcus01]

i am setting up a new tank and cant remember how much live rock per litre/gallon of water i need...

i want to use the live rock as the main filter ,i will also be running a protien skimmer,refugium with cheto and a calcium reactor

minimum 1lb/gal to as much as you can fit. i've seen 230lbs in a standard 100g reef.

IMO different rock has different levels of porosity and density, some light porus rock wont require using as much poundage wise as if you selected dense heavy rock.
I have a suggestion you may want to consider depending on what fish your going to keep, and the size of your new tank. If you have a large enough sump/fuge utilize that space for a portion of your rock and this will allow you a more open space in your display for the more active large fish.

the tank is going to be 475 ltrs and the res/fugi is 216 ltrs...its in the making right now i have to wait 7 to 10 days for delivery . so yes plenty of room down bellow for rock
