After a bit of looking in my lfs's I think I understand how to do a rugf system and I really like the idea. On searching the forums I see some people have issues with real plant roots invading the ugf and I really want alot of plants in my tank. So here's my thought: After laying out the ugf how about if it was covered in a fine mesh screen cut to size? Would this serve to cut off the root system invasion while still allowing good water flow up through the gravel bed?
Thoughts anyone?
