Dave,
I forgot to touch on the water quality issues in the last post. Let me know what you think about the following: My pond is built in sandy soil (less than 10% clay content) and is continually being repleshished by an underground spring (I really need to get more info on this to see how much is actually getting "pumped" in) and the FHM pond is going to recirculate water from the main pond through the FHM pond over a waterfall and through a 30-40' "stream bed" that will contain vegetation and rocks. The reason I'm saying this, is that I believe both the spring's replenishment and the sandy soil's drainage along with the flowage from the waterfall and streambed will act as natural filters and help clean up the water quality. Do you think this will help? or not enough to matter?
