Well i got some weldon 4 and a needle from a local acrylic guy today. He gave me the best price....free!!!
I need to know one more thing before i go on. IS it safe to use a 3/16" acrlic bottom? the sides r 1/2" acrylic.
flatzboy, how much was ur acrylic for ur sump? where did u get it at?
Mine is I believe .25'. I taped them all together first, they don't have to be tight when you tape them just to hold them together then I slide like 15 big rubber bands around the 4 sides to hold them tight together. I wouldn't use my hands the rubber band process works good. If you can't find any big enough rubber bands then use electrical tape because its kind of stretchy so you can pull them reel tight together like a rubber band.
