I'm new to this forum but you all seem very knowledgeable and active. I'd love some advice.
I'm planning a new pond system to work over 2 levels of my backyard. I have an upper level where I plan to build the main pond, and then there is a rock wall, and then a lower level that's about 4 feet below. My plan is to have the main pond on the top level then a series of water spouts leading off the edge of the rock wall into a barrel bog filter and then into a large bowl with aquatic plants (and a pump).
The bog filter I am planning to setup will be a large wine barrel full of aquaponics clay balls to give loads of surface area for bacteria. I may put a layer of pea gravel in a basket hanging near the top of the barrel as well, to plant some plants in. I'm planning to put a tube next to the barrel (perhaps a wide piece of bamboo) with a pipe leading into the bottom of the barrel. The exit spout from the barrel is lower than the tube, so the water will flow from the tube, through the pipe into the bottom of the barrel, then up through the clay balls, and out the exit spout (in theory).
The water will then flow from the exit spout into a large pot or bowl which will have a pump in it. The pump will pump the water back up to the main pond where it will come out a bubble fountain on the far side, so water flows the full length of the pond. At the point where the bubble fountain comes up I am planning to setup another small bog, this time with pea gravel, that is in a separate container sitting at the surface of the main pond, so the water would top feed into the bog from the bubble fountain, and then travel through the pea gravel and out into the pond.
The water will then flow across the main pond, and pour out the spout into the feeder tube again... and the cycle continues.
I've included a drawing which will hopefully help explain it.
I will have to work out flowrates and what size pump to use of course, but is this a feasible idea? Or am I missing some massive flaw that will make it all fail?
Another question I have is, how do I connect an exit spout to the side of a pond made of pond liner? I don't want to make a hole in the liner for the spout to poke out, and I also don't want to have to use another pump to raise the water up to the top of the liner. A channel in the liner is the only option I can think of, but then how do I attach a tube to the end of the channel? Just with silicone sealant, then put a rock on top of it to hold it in place, or something like that? Seems a bit haphazard. Is there some trick to that sort of thing please?
Thank you kindly in advance for any advice you can give!
