You are right, part of the $1000 costs is pumping, cleaning, testing, inspecting of the tank prior to filling with flowable concrete in the abandonment proceedures. I am also planning on a liner for the fish tank.
My big question is how many gallons per hour should I plan on for 500 gallon tank. Do you Know?
