Just for fun my friend and I (Geoff) decided to try to build some glass tanks. I am unsure what I am going to do with mine, but my friend will be setting up his tank as a display. Since Eric was headed into the city that day he gave us a hand with the build. Eric is the one behind the camera, he took all the pictures and helped build the tank. Thanks also to Craig for getting the glass. Specs my tank 24x24x20" 10mm glass 3 sided starfire 10x2" slot cut out on back glass for external overflow 12x6x5 external box double pane bottom his tank 31x31x18" 12mm glass 3 sided starfire 10x2" slot cut out on back glass for external overflow 12x6x5 external box Supplies Acetone RTV 103 Angle squares from rockler Lots of towels Painters tape gloves double stick tape So far we have just worked on my tank first. Since his was bigger we figured we should do my tank first and learn from our mistakes. Angle squares from rockler Taping off glass Setting glass on angle squares with double stick tape Glass all set up Deciding on how to start Back side before cleaning Front side Side view Mistakes Pull tape off faster We did not pull the tape fast enough which messed up the insides of the seams. We ended up having to strip the inside seams add more silicone and form the inside bead with out the tape. I used the pro-caulk tool which actually worked really well. Use MORE silicone than you think you need We still have to put the external overflow box up. I will post more pictures as it comes together. I'll also post some progress we have working on the bigger tank.
