Pipe Siphon by Apollo

[Apollo]

I read your post where you're using a stand pipe for constant flow with a constant level. My question is how does that system get enough oxygen to the roots of your plants? If the water in your GB never drains out the bottom, it just drains from the top only. Doesn't that impede somehow with the circulation of the water in the GB? I would think that the water on the bottom 2/3 of the GB would go stagnant.

I know the slots on my media blockers are a little too large, but I covered them with 1/2" to 3/4" cinders. The cinders stop the smaller media from plugging the slots, plus with two media blockers it should that twice as long to plug up and restrict the flow of water. Time will tell...so far so good, it has been right on the money every time.
