Aqua blocks seem very pricey. For my pond, I'll need about 100 of them, so I'm looking at spending $4000+.
Are there some cheap alternatives?
Note, I don't need my bog to support the weight of tractors or cars, but I do expect people to need to walk on top to tend to the plants growing in the bog.
If the purpose is to simply create a void underwater, could one simply buy four metal bed frames, ($100 each), cover them with chicken wire ($50 for a bunch) and have the same results, a void underwater that supports 12" of gravel?
Or could I loosely arrange a row of concrete cinder blocks? They have large holes in the middle. I could align them in a way that insures the water flows through them, and leave 1/2" spaces so the water can still seep upwards through the gravel above.
