lol free, as much as my 2 yr old tries to help she maakes a 2 day project take months. only thing i am unsure of is my return and tunze placement. thinking of getting a sea swirl for return. or leave it coming out the one side and put tunze on same side to push water from one side to the other, which in return will push the end water back into over flow. hopefully this coming weekend it will be fill with water and rock. just enough time for me to get more frags at the meeting
