Questions - Need some input

My boss brought me back 2 water bottles full of sand and water from Daytona to start my tank with there's lots of life in them (lots of critters in shells)

Any better suggestions for around the same price, or is there something way better that would be worth the money? I also am thinking that a closed loop setup might not be worth doing, by the time i get the plumbing and pump to get the water flow i want i could buy power heads that would ...
