So, it's the pond project that just keeps going! I setup the waterfall and I used the Atlantic Water Gardens BF1900 Filter/Spillway and it has a grate on the top to stack rocks to make a "bog", anyone done that before? Any suggestions? I saw on their website they put plants in it. And, if you at the pics, I did a couple of layers of underlayment on the blocks before the liner. I have a skimmer coming so, that's the last step before fish (although there is a huge and healthy colony of tadpoles in there now). Running all filters as a test right now; haven't trimmed all the flex-hoses to size yet either. It kind-of looks like a huge pile of rocks (probably because it's a huge pile of rocks). Going to have to figure out a way to green it up a little even though I'm no good with plants.
