Hi Poconojoe,
Thanks for your reply. I've been looking at your posts, and you're right. Our ponds are very similar, and we're in the same area of PA. I'm in the Reading area.
This brings up 2 questions (and I may have more). My bog will be about 18 feet higher than the pond. Do you have an idea of what size pump I would need? I'm going to use a DIY skimmer in a bucket to feed the bog.
Number 2 - what height did you make your spillway relative to the water level in your bog? I was thinking not more than an inch or 2 below the 12" water level. Am I close?
Thanks
I couldn't guess what pump you would need if your bog is 18 feet higher than your pond. You would have to choose a pump based on it's head pressure.
My bog water height is probably about 12"-14" above the pond water.
I have my pump on a string suspended above the bottom so it doesn't pick up any debris that may collect down there. The pump is about 2.5 feet below the surface.
My flex PVC from the pump goes over the bog wall. So, my guess is that the pump is pushing the water up about 4 feet.
The only specs I can find on my pump are that it's a Tetra DHP 3600 (debris handling pump) which is 3690 GPH and maximum pumping height of 11.4 feet. Like I said, it seems to be the perfect flow through the bog. As you probably know, you don't want the water to flow too quickly through the bog.
Hope this helps to give you a perspective on what you might need. Obviously you'll need a pump that is more powerful than what have, but at least my situation can give you a sort of benchmark.
