Glass always looks better, but not so much fun when it's time to rearrange.

I just made 4 tanks out of mr10 lexan. I am wondering if it can stop a bullet, will it scratch as easy or be as clear as acrylic. They look great but I just built them have yet to add water to it.

2 tanks are 43 by 18 by 15 and the other two are 43 by 18 by 12
I used acrylic glue and c clamps.
And I used the euro brace style instead of center brace.
If I'm not mistaken it should be 185ish gallons. Or 740liters. I'm going to run it from the top to the bottom of the rack with a 2kph pump and 2 fx4 canisters on the bottom tank. Like I said I just put the plumbing in an hour ago. 20170625_232818.jpg 20170625_232835.jpg 20170625_180036.jpg 20170625_180050.jpg

I'm curious if I should bother adding a silicone seal to the already bonded edges. I'm going to pressure test them tomorrow to ensure the edges are set but is the silicone really necessary? Obviously I want to seal the bulkheads but the edges are glued together.

I know acrylic but I know next to nothing about lexan. Do the solvents melt it like they do acrylic to make a bond?

I never use silicone on acrylic, that's a no no unless for non pressurized fittings like sump baffles. If you were to try it use RTV. I would use weld on 40 tip and pour.

But is lexan more like glass than acrylic? or more like acrylic? This is completely new to me

The glue I used dose bond the panes of lexan almost as if were melted together. I want to say lexan acts more like acrylic. It's flexible to an extent, it's light as a feather and unbelievably clear. How ever that's were the similarity between them ends. Acrylic is crazy soft and I can scratch it with the grit of my palm. Lexan has taken a shot from a sledge hammer and shows no sign of impact. It's goes even further my 53 gallon boxes are 1/8th inch thick. Acrylic would have needed to be 1/4 or better. Lexan is stupid expensive. Acrylic for me is $350per 8'x4' at 1/4 inch. Lexan Mr10 is $900 for the same sheet.
