When I press down it it, it bows / gives a bit but doesn't come loose. It's not as tight or immovable as a regular screen for herp & reptile tanks, if that means anything. Any idea if the tank was made this way or if this is something they added for one of the environments? If it was part of the tank, should I remove it or try to clean it?
Actually there was a lot of sand and a few crushed shells when we picked it up so I think herps were between the FW
. It had been sitting in the garage for quite a while and I'm guessing the tank is 10-15 years old, if not older.
