New tank plans sound good?

[Dasani]

Ok so I am going to upgrade my 20H to a 40g shallow rimless cube. I am going to transfer everything over from the 20g and use the 20g as a sump. So here are my plans:

Tank: I am going to build it myself with 3/8" thick glass and dow corning 795 silicone. It will be 28inx28inx12in.
Light: 250w 20000k mh pendant from fishneedit.com.
Filtration: 20g sump with live rock and sand and chaeto. Also an Eshopps psk 75 skimmer.
Flow: Mp10, koralia 1 (already have), and my return pump will be an Ehiem 1048.
Heat: 200w visi therm heater. I will add my 50w if the 200 is not enough.

Here is a quick pic on what I want it to be like:

Please tell me what you think :)

I'd go with a better pendant. A lumenmax, lumenarc, lumenbright, etc. Something with more spread. Or else you could have problems with not enough light spread/not enough PAR in the ends of the tank.

I love the idea. I was just thinking the other day about the same concept. I want to transfer over my JBJ to what you have above. I was thinking acrylic sides and starboard bottom. Also I was thinking about making the whole back side the over flow. Just a thought. Keep me posted great idea. Is the light going to be enough to cover the whole tank for coral growth?

The pendant is 12" long I think it will reach. Im going to have it about 2ft above the water so it should spread. Watch this vid, it inspired me and he has the same size pendant on a wider tank.
