Bump ;)
 
I don't think methylene chloride (the solvent used there) is recommended for aquariums. I did this for my sump build, and the seams were fine... for about 2 months under continuous stress before they ruptured. I may be way out in left field, but I think the 2-part polymerizing adhesives like Weld on 40, or 42 are better.

Someone please correct me if I'm wrong, I've been wondering about this since my seams blew out... twice.
 
Why would it matter what you used? Last I looked you were basically "welding" the peices together.....
 
Thanks for the video's..I've been wanting to actually see someone do this..

I personally recomend weldon 3 ;) I wasn't really paying attention to whaty they used.. My bad. But still Weldon 3 Looks exactly as demonstrated ;)

Well I used weld on 3 and weldon 40 on my 250 ;) Adn I believe Milkman did his large tanks with weldon 3-4 or somethign along those line :)

It does look that way, but the crap I used looked that way too. When I took it out of service to try to repair it, I could basically pull all the seams apart by hand... and I'm sure everyone is wondering, but yes I did everything else properly - clean routed seams, applicator bottle just like the video, etc. The cement I used didn't have a weld-on logo though, it was just sold to me by the plastic shop dude as "the same thing" and it's called methylene chloride. I also saw a post somewhere about someone's 200gal tank breaking, and someone mentioned that the solvent welding process isn't recommended for huge tanks like that, to use the polymerizing stuff. TBH I wish I could find more info on it.
 
Very cool video! I am shure going to try it out soon (first on a small 30 gallon or so and maybe later on a bigger tank!)

Btw, people can download this video to save on your computer by using for example, youtube grabber.
