Looking for thoughts/ideas..........

I'm looking for other ideas as well and had one thought - another piece of glass. If the glass was cut so it sat directly on tank bottom and not on any of the silicone holding the tank together, you'd have absolutely no chance of detritus getting under there. That would mean at least a 1/4" or so of perimeter where detritus might accumulate, but if you set up your rock right, you could easily it siphon out.

Don't know how thick the glass would have to be to distribute the weight of the rock evenly. Any ideas here?
