carey said:My 29g cube holds exactly 18g of water after rock and sand displacement.
carey said:I have almost 50lbs of lr and 30lbs of sand in my cube. it also depends on how high you fill it. To run it seems it has to be at the upper lip of the tank.
tlkng1 said:Yeah...I noticed that little difference as well. Went to the LFS and bought 7 gallons fresh saltwater and 7 gallons of water "in-use" by their own systems....after filling with JUST the water and 8 pounds of live sand, I had about 4 gallons left. I only removed about a half gallon of water to accomodate the liverock.
