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.
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.
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.
