Baffles In Glass Sump?

Hey about to start my sump, its a 30gal, I was wondering If i had to use glass baffles with a glass sump? I think i read about it on a forum, but maybe im crazy iunno, what do you guys think?

 

U can use glass....acylic is fine too for baffles bc there isn't ne pressure.

 

I'd use acrylic pressure locking baffles. Do a search, I just them myself.

 

Either is fine. I used glass in mine cause it's cheaper than acrylic

 

My acrylic baffles on my glass tank have been holding just fine for 2 1/2 years.

 

I think most people recommend using glass. Because silicon doesn't hold on to acrylic. That being said I used 1/4" acrylic and used 3 times the amount of silicon. I used G.E. silicon ONE. Do not use G.E. # 2 it has antifungial added to it.

 

thanks! yeah at my homedepot ware store there is GE silcon 1, but doesnt say aquarium safe on it anywhere, apparently they took it off the label? Went ahead and ordered in marineland silcon instead, cost a bit more but better safe then sorry i guess

 

I have acrylic baffles no problems

 

Silicon does form a weak bond to acrylic but bc there is none to very little pressure on baffles acylic is fine. Ill be using acrylic baffles in my new 120 gallon sump. Currently using acrylic in my 10 gallon refugium
