    Default 1/8 or 1/4 inch glass?

    Will 1/8 inch glass be good enough to make the baffles in my 10 gallon sump or should I go 1/4 inch? The sump will be a regular 10 gallon glass tank from walmart and I think it is only 1/8 inch thick.

    Why not just use acrylic? It's a lot easier to work with.

    From what I have read acrylic and silicone do not bond very well, Is this wrong or would it work ok?

    It's fine for a sump application. All of my sumps are glass tanks with acrylic baffles. Just be sure to get the 1/4" acrylic. I tried it once with 1/8" to save money and had to rip it apart because it collapsed under the weight. I didn't think there would be that much pressure on them. Live and learn.

    I am in the process of doing the exact same thing with a 10G. Making a Fuge out of it. I plan to use 1/8 Glass because Acrylic does not bond well to Glass. I have friends that DIY these all the time and this is based on their advice. Glass baffles for Glass Sump, Acrylic baffles for Acrylic Sump. Aquarium Silicone for Glass & Weldon for Acrylic.

    either acrylic or glass works fine, it's up to you guys. Acrylic is easier to work with, but if you can get glass cut to the size you need for the price you need, go with glass.

    Generally speaking,silicon doesn't bond well to plastics long term.If you scuff up the edges of the acrylic with sandpaper it'll work better.Since baffles usually don't have a big load to support its not a big deal anyways.I use 1/8" glass baffles in my sump because thats what Home Depot had.If i was to go to a glass shop,I'd probably just go ahead and use 1/4".
