I just got through putting together my first DIY Overflow. 1/4 inch cast acrylic and Weld On #16. I had #3 but no applicator bottle. I thought the #16 would be a little more stiffer than it was but we got to work.
First question, is #16 as strong as the #3 or #4?
Second question,After gluing it together I put a bead of it (#16) all the way around the assembly, will this help to seal and hold it together or was it a waste?
Last question, I have about 10 linear inches of overflow (8x1x1), Will this give me the amount of flow I need for the 45 gallon tank as long as I have a pump that will supply it? (looking at a mag7 with 1" return from sump and two 1 inch supply to sump)
I will try to show pics. All critiques are welcome. I know that I still need to put the airline in the top of the oveflow along with the drains.
