I dont know if its a leak, the pond was left outside at the lfs i work at and (it was empty) and I think it might have absorbed water (like a sponge) and when I filled the pond up the water was being drained out of the wood, atleast I hope so. The water isnt coming out of the pond anymore, so I hope when I wake up tomorow there will be no water on the ground. I think on Thursay I will be adding my male motoro and see how he does. I will be contacting Pat at amazon stingrays as well and buying her CB female motoro that is 8 inches and also a female that is 10 inches from a guy in my city. I am VERY excited
