Bonding glass to glass- building my Coast 2 coast overflow...

I'll spare you the Bond jokes....

I had 2 x 70 7/8 pieces of glass cut for my coast to coast overflow for my 180 build.

I was going to use reef safe silicone.

But then I thought, to bond this- why not use Epoxy- which is also reef safe? I can seal it with silicone.

I'd like to hear from people that have build an overflow like I'm building, and anyone elses thought too!

 

Hi bud. I dont have coast to coast but have a internal corner box. What epoxy were u thinking about using? Its usually pricy from what iv seen, where as silicone is cheap and proven. Sorry i dont have any first hand experience with using epoxy but, hey, its a bump all the same.

 

silicone it. the RTV silicone you should be using will have plenty of strength to hold it and then some.

 

Thanks!

And, the RTV silicone is Reef Safe?

 

Silicone will be a much cheaper solution. An epoxy will also need some sort of profile to bite onto considering it is only a mechanical bond. You could do it but it would be much more of a headache than what it is worth. If you really wanted to go for a sleek look you could use reefsafe krylon paint (I believe it bonds to glass) and black silicone. Personally, thats what Id go for.

 

The black silicone I got from glass cages was rtv 100% silicone

 

i used marineland silicone on my coast to coast

 

Thanks to all!

RTV silicone it is!

I actually planned on painting the front pane of the overflow as well.
That way, when you looke across the front of the tank, you wouldn't see a trough of water running below the surface level. I plan to paint the back and the front of the overflow the same color.
Purple, Blue, or Black- still undecided on that too.

I painted My current 125g has Black

 

This stuff is kinda hard to find,
but I found it at Grainger supply.

2 tubes of the RTV100 series- 11.49ea.

 

Good deal and price. the reason we use RTV is it is adhesive vs just sealing the joint. Wear gloves and a mask when you use it and make sure the tank sets for 72 hours before use with SW. you can water test in 24. This is the exact stuff I used when I re-did my 225.

AH-HA! Found the pics
