Hey all, I've got a pond-predicament and was hoping you would be able to help me. Basically, I've spend a LOT of money on an outdoor oval shaped pond about 3' deep, 7 ' wide, and 5' deep. I've lost a lot of money trying to figure out how to seal the pond from leaking. I eventually ended up tiling the final thing, but now there is algae build up frequentyl and I have to drain and refill the whole pond. What do I need to do to keep the water clear? There is nothing in the pond except water (no plant life or anything)
