Today I had a piece of glass cut for a new glass top. 4 stick on rubber feet create what I think is going to be the amount of airflow I've been testing with the hinged top. gives about 1/4" of air space all the way across the front and back. this also gives me about 1/4" more headroom, allowing me to resposition the loc-line more easily. a side effect: there is less vibration noise as well. the tank is almost silent to begin with.
