Ponds been up for a few weeks now and was just starting to clear up. Yesterday I did my 10% water change as I have every saturday. well after I was done a buddy was looking at the pond and he noticed a crack in it. So I had to drain the pond 2/3rds of the way down. I used a 2 part epoxy to seal the crack and let in sit over night. This morning I went out and filled it back up. Well the 2 part sealed it for the most part but it is now a trickle. So I drained the pond again and tryied some more epoxy on it. Thinking of just getting another one from HD. Hopefully this seals it. I was just starting to see the light at the end of my tunnel as far as my cycle and now I would have done well over a 100% water change this weekend so I guess here we go again. :regular_waving_emot::::::::
