Well crap! I just put some water in the pond and found out my stupid filter leaks like a sieve. I used tank fittings which are supposed to be water proof. Not the case! Now I have to come up with a whole new filter system quickly after spending a fortune on this one. I'm so discouraged, plus after all this, the tub is full of water and built inside the box so I am going to have to find a way to bail out water. Grrr.
