Baffles in Glass Sump

[Duff Man]

Is there any reason that I can't use acrylic baffles in my glass sump? I know that using glass and acrylic will cause problems when trying to make a water tight seal, but anybody have bad experiences using it for baffles? Just wondering before I have some plexiglass cut.

I have several tanks with acrylic baffles in glass sumps. No problems.

if you are have dsb in the sump make sure it thick enough that it will not bow and pull away from the glass

I am going to use 3/16" thick acrylic and will first tack it in place using an epoxy stick. After the epoxy dries I will put on the silicone. I think that should hold pretty well.

I don't think the silicone sticks to acrylic...

I currently have an acrylic sump with acrylic baffles and silicone is the only adhesive. They haven't budged at all.

It does stick to it just not as well as glass....I also used acrylic and glass sump and a s**t load of silicone and it works great!!!!

Glass on Glass or Acrylic on Acrylic is a better option. The problem is that silicone doesn't stick to acrylic very well and acrylic glue doesn't bond glass very well. I know people do it anyways and many times it will gets the job done ok. So if you wanna take the road less traveled then knock yourself out

All three of my sumps are glass tanks with acrylic baffles, the oldest one is 5+ years old, and the silicone is working great.

I would go with 1/4 acrylic.
