has anyone replaced the front glass on a tank before?

Silicone works for holding the tracks in place.

If you think your tank is low and wide enough to skip the lower vent like in the link, I'm not sure of the best design for the lower track. One thing the vent does is give a horizontal shelf for the track to sit on. The track will be wider than your glass, so you might need to find something that can widen the piece you add to the bottom front of the tank. Something like the plastic trim with the "L" shaped profile like they use in the link might do the trick if you support it from behind with a second strip of glass.

i think ill do exactly that design. its not a low tank at all. it actually might make a nice tree frog tank. finding those e profile plastic tracks around here will be fun. might just order them online. Thanks for all the info Brian

No problem!

After a few months of searching for the E-channel locally (and not so locally), annoying and confusing many hardware store employees in the process, I came to the conclusion that no one in Canada has ever made a cabinet with sliding glass doors. Even the usual wizards at Lee Valley were no help. A few months after I had abandoned all hope of getting E-channel and avoiding shipping costs at the same time, I found it in a random aisle at Home Hardware. Not the aisle with the other long plasticy thingies like the L-profiled trim, but something random and out of place. I had even shown employees pictures of what I was after.

So check your local HH. They also sell the cheapest aquarium safe silicone I've seen (their house brand, comes in clear and gaudy white if you want to make something extra ugly).
