Need opinions on this acrylic cube

[Mrfish55]

The listing does state it is cell cast but looking at how tight the radius is on the corners I would suspect they are glued up and then machined to give the rounded edge, my old tank was 1/2" bent and the corners were nowhere near as tight as those look. Perhaps an e-mail to the seller could clarify the construction of this cast cube

14" deep with 3/8 glass and there will be bowing??? I dont think so.

It's acrylic, pay attention

Its 14 inches deep, 16" long and 3/8" thick there might be 13.5" of water in it bust most likely 13" there isnt alot of pressure, that acrylic isnt going to bend.

You're right what do I know about a few mm of deflection

Cool graphs! How'd you do those up? If i'me reading it correctly the 16x16x14 should (in theory) only deflect 1mm?

Submited an offer to him, so I should have the tank in the next couple of weeks!

EDIT: He just accepted it, whoot. $90 instead of the listed $114, almost takes care of the extra shipping cost to canada

I'm looking for advice on hole placement if you guys dont mind.

The system is going to be powered by a canister filter to provide all flow (kinda like ninjafish's tank)

I'll have the drain in the bottom of the overflow (as usual) but I'm trying to decide where best to put the return. The way I see it I have two options.

1. On the back, about midway up
2. On the bottom, in the middle, then angle the return a couple of ways to provide some good flow.

Thoughts? I think I'm leaning towards #2, that way we wont see any tubes on the outside of the tank (I'm going to get a second hole drilled in the overflow to provide a dry chamber for the light/heater cords)

Thanks!

It's a finite element analysis (FEA), I designed a template which works with the software and does a simple analysis based on basic tank design for whatever size I desire. I can also add bracing and various other features if needed. Front to back or side to side you may see up to two mm total but it bows out less at the top so it'll probably be close to about 1mm total. Basically you won't really notice it. You may notice a little difficulty in macro photography in the red area but that's it.

I'd vote for option #2, you can build a center structure of rock to cover the return outputs.

Got a message back from the seller, shipping is an extra $30. So all in all it comes to $190. From what I had investigated previously, it seems like a great deal. I wanted to get a small starphire rimless cube, and I believe the quote I got a while ago was much more (without shipping)

I think i'm going to go for it, I'll let you guys know how it turns out.

domestic cell cast it is. I'll ask him about the construction and see what he says. A few people over at RC have his tanks and are very impressed with them. The price seems reasonable to me.
