Acrylic baffles and Silicone

[Bug_Power]

search reefcentral....I talked with a guy who did his research in college and now works in the field with silicone. He agrees it will bond to both surfaces however the mechanical bond with acylic is less then with glass, but for most purposes aquarium related it works fine. I'm sure if it will hold 180 and 150 gallon centerbraces, your baffles should have no problem. If you take a bit of 200 grit os so sand paper and go over your edges it will stick even better. Just don't try flame polishing your edges of your baffels then siliconing them on. It may only hold 60or so pounds then.

I'm going with a YES, it works. "But How..." you ask! Easy, you just have to leave about a 1/8" on each side and make sure to silicone both sides. For the middle baffle it is difficult but as long as you make sure the silicone fills in the sides you are set. I did it to a 30 gallon AGA and a 10 gallon AGA when I first started in the hobby. When I tried to pry off the acrylic baffles later on i ended up cracking the 10 gallon because I was putting in so much force to try to pull the acrylic away but it wouldnt budge. It works! I dont care who says it doesnt, it does because I did it. I used the DAP Aquarium Silicone they sell at HD, worked to perfection. Any questions feel free to shoot me a PM. HTH

I have 1/4 inch plexi glass baffles and the bond is pretty strong. Probably not as strong as glass to glass but strong none the less. There is now way the baffle would detach itself unless someone actually did it manually and with force. I dont know if its the same with acrylic but plexi worked fine.

Most of my baffles are glass. I got them cut to size (12"x12" for my 55g sump/fuge) for about a $1.00 each at the local Ace Hardware store. It's the thin glass, maybe 1/8", but it works fine in the sump as there's not a lot of water pressure like Matt pointed out.
