How Much Rock

[mbu man]

could someone remind me what the ratio of rock you should have to the volume of water, cheers.

A good rough guide is 1kg per 2 gallons of water, though your planned stocking will affect the rate, as too will the rock as mroe dense rock is less effective at filtering than more porous.

Yea I agree with andywg as ive read its approx 1 pound per kg so works out to approx 1kg per 2 gallons!

do you mean 1lb per 1 gallon? Not 1lb per kg? Lol...
