weld-on substitute?

[fmelindy]

I'm going to practice by trying to build something similar on a much smaller scale, I need a skimmer fro my nano with no sump. I don't see why a recirc can't work for that as well, with a small feed pump immersed in the tank proper and outflow going directly back in the tank from the skimmer placed slightly higher than the tank itself on an adjacent shelf or cabinet. Does that sound like something that would work?

Look for a GE plastics or SABIC (new name) listing in NL; typically your best source for weld-on and acrylic.

Apparently there is a location in Halifax,

Just curious. Where are you getting the acrylic for this project? They should certainly have solvent....

[fmelindy]

Yes, they do but they're charging $42 for a can of weldon #3! And they don't have either of #16 or #40, which I'd prefer given this is my first such project.

You want to use 3. 16 is just sloppy and 40 is a 2 part mix that it a hassle to work with. A bit of practice and #2 or 3 will be fine.
A small can of 3 should be a couple of bucks.

3 is fast like Methylene Chloride. Use 4 instead to give you more time. 40 is good for not so perfect joints but has a short shelf life. 40 works well for pvc to acrylic. 16 sucks in most cases.
