I agree, cast acrylic is used etensively for machining purposes, if you search enough on it you can find hardness ratings. Basically what that means is the strenght of it.
Cast is usually made by pouring the resins into a mold and put under pressure to form it. Extruded similar but gets extruded through a machine, kinda like a sausage stuffer.
Extruded usually has machine marks whereas cast does not, better optical clarity is acheived with cast acrylics.

Extruded also has stress in it from the cooling process, which isn't as controlled as a cast piece. Those extrusion marks can also be stress points. The skin on extruded is tighter then the core IIRC, so when you glue it, it has a high chance of cracking (stress cracks), same with drilling, it's more likely to break out or crack.

Anyone familiar with the 4" to 6" flex coup. made out of rubber? I was wondering why this wouldn't work for the trnsition pc to the coll. cup. The only drawback I can think of is the metal (very rustable) hose clamps. If I can figure out how to resize my pic (enough) I will post it.
While at lowes I also ran across a thing called an EGOUT (cost: 6.98) its 4" (allthough a 4" pc of PVC won't fit in it). It looks like a standard coupling but has a rubber seal inside each end, I found that a 3" coup. fits almost perfectly, a little tight but nothing a little KY won't fix (right Pikey). If someone gives me a good reason NOT to use the flexible coupling then I might give this idea a try.
The flex. coup.will only work for a 6" reac. chamber but the EGOUT should work for any size. I'm wondering if a pc of 4" dia. 1/8" wall acrylic tube would fit the egout, then you could scrap the 3" coups.

i do not think ER use diff size sedra's to save on money .. I believe there is a certain ratio for each pump you should follow . Your skimmer is lookin good grreefer , i would be afraid of using a sedra 9k though .. im gong with the 5 ( price isnt really the issue on the pump its like a 15 dollar diff ) but i think ER uses certain size pumps for a reason , not to really save on pricing . Goodluck though!
Also off topic , the baldwins suck at acting.

I ordered the 6" tube before the sedra. Then I looked closely at the ER specs. and noticed for a 180 gal. tank I would need one of the mid sized ER's (one with 2- 5000's). So, my plan was to buy a 9" pc of acrylic after I see how this one works. Practice makes perfect, right. I want to make absolutetly sure I fabricate a $125.00 pc of acrylic properly the first time, I can live with messing up a $19.00 pc..
Versus: How big is your tank?

14 ten gallons heh 
getting a 120-5 just saving up money to buy everything else first ( basically the lights ) and researching is becomming a pain because WAY to many people have different opinions.
just wanna get everything so i can take pictures for my journal .
9" = $$$$ i ended up ordering a 12" of 8" od , going todo the oven cook acrylic sheet method for the riser. I dont know how you thread something so large but I want the connection to look similar to a Bubbleking
My main problem at this point is figuring out how large diameter wise the tube after the riser should be. I think 4 1/2 is way to large.
skimmer will be fed via overflows
