Another thought, is there anywhere in the "calculations" for a bog that actually covers the consideration of # and or % of plants? Since the function of a bog is dependent on the presence of plants, how many little rootlets [
] are needed to make it functional?
Again, what I'm doing in the turtle section [a few square feet of gravel, 3 or so inches deep, with lots of little plants stuck in, sprouting roots] is not a bog, but it's got to be doing some good just by being there, right? There is good water flow via an overhead spray bar, and when I occas. stir up some gravel, there's hardly any sediment -- it stirs clean. Now, since the turts aren't fully utilizing their "facilities" yet, any waste products are coming from the water itself (spray bar water comes directly from the pump), and anything the goldies and/or "toad"poles are leaving behind. The plants are looking good.
Really, just curious as all I've read about bogs covers the % of the pond surface they should cover, but not the amt. of plants required. Food for thought [pun intended!]?
