I did the tiles on a little nano I had and eventually took them out because I got a load of detritus between them.
Not sure what you could do to fix it
Thats what I thought would happen. When BB first became a big thing we used custom cut cutting boards (starboard) on the bottom of our tanks. Eventually detritus would build up and reek all sorts of havoc.
People started to silicone the starboard in place so that nothing could get underneath it. That worked much better.
