I personally dont think that will be enough LR
. You`ll need about 75 to 90 lbs to start. They kind of suggest 1.5 to 2 lbs per gallon but if you can get 1 lb per gallon you can probably do it. A suggestion would be get the 25 lbs of LR
and get 50-60 lbs of Base rock. It will become live over time.
