The size of gravel I see is to small and doesnt allow for much water storage for the whole area of your basin. Did you add large stone in the bottom and gradually work up by chance?
These were the reasons I asked the question about use of the matrix blocks. The small size of the gravel not only reduces water capacity but facilitates much easier clogging. Everyone does things differently, just wondered why.
