    Are you using glass or plastic? Plastic will bend with the weight of water it is retaining, there isnt a set "thickness" it is more of, it needs to be thick, and strong enough plastic sheeting or glass that it wont bend/break.

    for glass, 1/4" is sufficient. i took two equally cut sheets of 1/8" pane glass which is very cheap and glued them together for 1/4" and it saved me a good bit of money.

    if the tank is glass, you need glass baffles. silicone, or weld-on, will only adhere to the material it is intended for. and will not create a proper seal or hold on the other material. this is why you see a lot of folks have baffles move or shift or fall apart after time.

    good luck!

    For my sump, I used the thickest piece of plexi that Lowe's sold. I'm not sure how thick that was though. Sorry.
