Are you planning on having your outflow pipes under the gravel or are you only planning on putting gravel up to them?

I placed my outflow pipe near the top in mine so the tub does not show much.You can still change yous if you want to raise the gravel level by placing elbows on the outflows.I also have a layer of course gravel in the bottom.

Great easy fix Ronfire! Didn't think of that. Not sure what op had planned but may do that with my tank bog.

Wish I thought of that for mine, would be easier to hide the outflow pipe. Could just have had it overflow into the pipe instead of a colector pipe with holes in it.

How would I do that now that there are holes in th tank?

As ronfire said just add pipe and elbows to your bulkheads and extend the overflow pipes up higher. You don’t need to change the holes.

If your pipes are below gravel , they will clog with the gravel. Any type of screening you use will clog quickly.

I thought the return pipes needed to be below the gravel. I am so confused :(
Tell you the truth, I have gotten a little loss here also.

The input flow into the bog needs to be below the gravel, full of holes slits etc. I have my openings in the pipes facing down with a extra piece of liner between the pipe and the bog liner.
Then you need to have a exit back into the pond. Pipes etc.
Some people put in a clean out pipe that usually sticks a bit above the gravel. I don't have one.

Just from experience I would recommend putting a concrete footer or a thick layer of gravel underneath it. A few years ago we had a heavy rain and the soil shifted causing a leak in ours without one.

ashirely If you add a 90 elbow to the inside fitting and turn them up you can add a section of pipe to that and set the water level in the tank to as high as you like. The water from the bog will overflow over the top of the pipe and return to the pond. The fittings inside the tub do not need to be glued, they will stay together well as there would be no water pressure in them.
If I was not about to rebuild my pond I would change my outflow to work like the above instead of a collection pipe with holes in it, much easier to set the water height. Wish I thought of it earlier.
You could have one outfloww higher than the other, one would be the main floww and the other as a backup in case the first gets cloged with plants. When you see water flowing from the 2nd pipe you know the outflow needs attention.

We will be making this modification this weekend. Have to make a run for more pipe to finish the job.
