Type of glass for baffles ?

[FullPull]

I've got a 29 Gallon lying around doing nothing and was going to use it for my 55's sump. My question is....What type of glass do you use to make the baffles out of?..Is aquarium glass tempered or hardened?....Just needed to know

window pane, its 3/16" thick. you can get your wardware store (Ace) to cut it almost on size. i have never checked Lowes or Home depot. measure about 1/16" under the inside measurements width. that leaves room for adjustment and silicone. (100% pure silicone, only) REEF-ON!!!

Yep. Window pane here same thickness 3/16". Works great.

I have used 1/8 inch glass from HD. As the water filled from the intake side to the return side, each glass broke. It was not a complete loss, I learned to cut glass with those pieces. I went to a local glass supplier and found that I could get the same size in 1/4 inch at the same price as HD's 1/8 inch. Another lesson, life is full of them.
I have worked with acrylic and prefer to work with glass. I would have made my overflow with glass, if at the time I had the tools to cut holes.
This is a 20 gallon that is under my 55 gallon tank.

How did you make the silicone so clean looking and not smeared the space looks so small between each baffle?

I only silicone on one side. I start on the intake side and seal it then the next baffle is siliconed on the side away from the first baffle. I continue this to the end. If you make a mess use a razor to clean up the silicone. Wait untill it dries first.

Nice job on your dngspot I may consider glass baffels for myn. I had planed to use acrylic, but like glass a lot better.

Wow that holds? I just assumed you needed to do both sides. I made a mess with silicone and a dowel doing the "inside" of each of my baffles. Good to know.

real clean job dngspot...I wish I had a 20 instead of a 29 to use. A little better size to work with under the stand, but I have a 29 just lying around.

I would suggest putting a line of silicone where you want to put the baffle and then move the pane into the silicone. If the water will be moving from left to right in the sump than move the pane in that direction, it will create a bit of a lip that will help secure the baffle evenmore (of course this was for acrylic baffles that are weaker so they needed the extra support).

I've read several posts with people trying that and it not working. Not sure if it's the size of the sump (and the weight of the water pressing against it but it seems to be very hit or miss.

Yeah, this is the technique that I used and it worked pretty good. I used 1/8th glass and it worked good, however, next time I am gonna try acrylic and see how that works!!

Could also be the width, they are cutting it too small.

I've used tape whenever I siliconed. Just tape down 3/8" from the seam and then after applying the silicone use a wet finger or dowel to smooth it out. Pull that tape while its still wet. Voila, nice and clean lines.

That's a great idea, I used glass that was 1/16th of an inch less thick as the tank and it works perfectly.
