Help assembling a glass box
 

I am ready to assemble a 4 sided glass overflow box, do I silicone all the sides together at once or do the back and bottom and allow them to dry then do the sides.

Thanks

You can do them all at once. Just have lots of masking tape to hold it together while it dries. Also clean all the glass with vinegar and newspaper to ensure good adhesion.

Thanks for the info, I'll give it a try, I've siliconed baffles in my sump but this will be outside the tank so I'm a little nervous.

I used acetone to clean the joints on my sump. but vinegar is probably a safer choice. And cleanliness is probably one of the more important things for assembly
