How to make a drip/waterfall set up?

[mikeg]

i didnt read any other comment so srry if i repeat. for my water fall in my crayfish tank i just went to a store in vaugh mills (a huge mall down the street from me) one of the stores sell wall, home, indoor, our door pound garden, fountain. i asked for a small fountian pump (cost $15) then went to home lows and bought flag stone. got the bigger ones and placed them on the bottom, and small ones on top, i also but it on a very slight angle to ensure the water to go forward once i turn the pump on, i filled my tank about 10 inches the part that was in the water i put live plants that part out of the water i used fake plants from a LFS. by the end i had this nice flag stone water fall with a slight tilt forward u would have to stare at it to tell, cheap and easy new project (what i like about the flag stone is u could alwasy change ur mind on the looks) but it prob wasnt a good idead to go it for my crayfish he keep crwling out of the tank so i had to take it down
