Not sure having the water run clean on a backflow proves it isn't caking.
True. but over the surface of my bog I have zero areas that have a strong flow of water, ie channeling. It perks up over the entire surface.

I did, one time, dig down to the bottom, x years ago, in a few spots. Everybody was saying the gravel water would stink unreal. So wanted to see if true, nope nice clean gravel no smell, no debris no caking.

I don't think you understand the basic principle of the bog. It is not to allow water to flow trough the bog much like your shower or even matala pads in a small or even a 55 gallon drum. The entire principle is to SLOW the flow wayyyyy down. Not to pump 10000 gallons through but to limit the amount dispersing the flow slowing its progression almost as much as you can. In my blog you can find a picture of papyrus that was grown on top of an aquablock. It looks like a brilow pad very dense not much will get through that very quickly at all. And that is what we are looking for and why the bog needs to be 30 percent if not more in surface area to the pond.
Now for every action there is an equal and opposite reaction, we all know this theory. And as one area does clog the water will find the next path of least resistance. In the mean time this muck is home to countless aquatic creatures. Mother nature purifies water in three basic ways .
1. Evaporation
2. Ground penitration through sand,lime stone etc.
3 Through the wetlands. No not so much by forcing water up through the bog like we do but it has the size advantage tgat we do not.
That is where the matrix blocks come into play its to alow the water a place to sit loose the flow and have time to let heavy solids drop out of the water and in that area is also a colony of organics that call that decaying plant and fish Waste five star dinning. It's not what we as humans see as anything but mud to our selves but spend enough time with environmentalists and youll get tge picture if they don't drive you batty first.

So any thoughts on best bog pipe layout for a half circle shaped bog? The flat side of the half circle faces the pond. Water comes in at one end. I was thinking two runs, one parallel to the diameter of the half circle and then another sort of diagonally across but worried about dead spots. Maybe a grid layout with a central run and then capped branches and then only one cleanout? Just seems like more work...

as long as you keep the pipes more or less down the center, it shouldn't matter as the water will always find the path of least resistance, flowing up. If you worry re more water escaping near the inlet hose and not as much at the far end(s), you can put less slots at the entrance and more at the end, to help balance. But it isn't that particular. Were it mine, I'd send one large pipe down the center (I used 4" drain tile piping = corrugated, flexible polystyrene without holes) and cut my slots about every 4", laying the pipe with slots up. In my case, I used no centipede and snorkel but something that works similarly; layers of graduated size round stone. 6-8" first layer, then 2", then pea gravel. About 12" of each. This method is a lot cheaper than using the Aquablox system but a bit more labor to set it up initially.

Mine is two runs, bog 4.5 feet wide, 27 feet long. Slots down, no clean out, just pea gravel. Been running for 10 years now.

I"ve seen people do one run down the center with "arms" coming out of each side, spaced down the whole run. And I've seen one run down the center, period. Both seem to work. So how much do you like working with plumbing? haha!

I myself for the peastone bogs prefer that the pipes be no more then a foot apart this way there's no dead spots the entire bog gets fresh supply.it can be main trunks with branches coming off or it can be just a couple or even one main pipe. But more importantly is to keep the pipes away from the sides as the. Water will just run up the sides instead of filtering through the gravel. I believe you can't have to many pipes in the baffle or to an extent to many cuts in the pipe basically 6 inches apart. And only cut less then a third into

My manifold has two 10 foot long 2" pvc pipes running parallel.

Don't worry about even distribution of the water.
Believe me.
I was amazed.
I see water percolating up everywhere in my bog. Even where there's no manifold below. Literally every corner has bubbling at the surface.

I noticed I did not say much about the clean out pipe, You can stick a hose in it to flush out the under the pea gravel pipes if they ever get clogged.
I realize this is a very old post but I was recently pointed here and this statement is something that precisely addresses a question I have. If one end of your bog piping is connected to your pump and the other end has a cleanout that you are sticking a hose down into...where exactly are you flushing a blockage TO? Where does it go?

I did not add one, but most likely you have a ball valve on a pipe that goes out of the bog , open that and the fluid goes out into the yard.

@LuapYllier - you can also build your bog with a "snorkel" unit that allows you to drop a pump down to the bottom to clean it out if need be. We built ours with one of these - a clean out pipe wasn't practical in our particular situation. (Having said that, we never need to pump it out as there's really nothing TO pump out - it has stayed very clean.)

For my bog, there is enough water pressure that if I open up the cleanout cap water comes flowing out. If there was gunk down there right now it would just come to the surface of the bog and get worked on by the same bacteria and plants filtering the pond, now it just won't be stuck in the bottom of my pipes. I could also screw on a discharge hose if I wanted to since it is a threaded connection. Would be one way to partially drain the bog.

The idea behind the clean out is to disconnect the pump or have a diverter valve . So on the end you have a ball valve or a cap that you remove and place the hose there. Open the pump end and back flush the system. I have not heard of to many who said wow you won't believe all the sludge that came out . It's more it was murky for few seconds then ran clear. I'm indifferent to the clean outs.

.With my setup, I leave my pump running and just open the caps on the end of the clean outs. The pump flushes out any debris in the piping.

This is pretty much what I do. Use my pump to flush out the pipes. It's not a back flush. I guess it's a forward flush.

I have two clean-out stacks at the end of my (two) manifold legs. They are each about 10 feet long and are made of 2 inch PVC.

I turn off the pump, open one clean-out stack, jamb an extra piece of hose in it aiming at my garden, turn the pump back on and watch the water shoot out black until it clears after about 3 seconds, turn off the pump, screw the cap back on and repeat with the second stack.

I'll do this when my spillway returning to the pond slows down a bit, maybe every 3-4 weeks. After the flush, the spillway volume increases to normal.

If I didn't have the clean-out stacks, I'm thinking it would still be OK. The flow of return water never gets close to stopping, it just slows down a bit. Maybe that slowed down flow is actually the correct flow and flushing is unnecessary, I really don't know. I do think the water should travel through the bog slowly, not too fast.
So, is my flushing actually counterproductive? I really don't know... But, I'd rather install the clean-outs and have them just in case.
