will this sump/refuge design work!!!!!!

[ludiNano]

The 29g display will have 5''x5''x5'' overflow box from austinoceans.com w/ 1'' drill. And will drain behind a thin wall in basement to sump.
Ok so the pic is very crud.....
The sump, a 20g long, will house a octo PS-120 that will over flow to the main area that will house to pumps. One that will pump water up to the refuge and one that will return it to the main tank.
The refuge, a drilled 10g, will sit above the sump. It will over flow back to the sump and be returned to main tank by a Reo 2500. The return will come back up into the overflow box an exit out an educator coming off overflow box bottom.
I was going to just have this all in one tank, but i thought i read that its better to have less flow in the refuge than a drilled tank will put out ( 600gph 1'' drill) and i could control it better. (any suggestions on pump up to refuge 14'' up aprox.) And i found this cool L shaped stand, the lower part only sits 16'' off ground.
From what i can tell it should work the sump is below the main tank, and refuge is above the sump, but still below the main tanks drilled hole. I will have a few battery backups to in case the power goes out. The only thing i may add would be a couple over under walls in sump for less bubbles.
Sorry if its a little wordy but i will take any criticism you have to better this system. Thank you in

do you ever run into heat problems, and what did u use for overflow in refuge

here is the pic of my fuge as of tonight. i use a mj power head to suck all airbubbles out of the overflow. i used pvc for the tube to go over the tank and just a regular over the tank overflow to flow back to the sump. i had to use a mj that i got from my crudy seaclone skimmer to pull out bubbles cuz i overflowed my refuge a few time cuz the flow slowed down alot though the overflow with bubbles building up in the tube. now i have no problems with overflowing.
and to answer about heat problems: the only problem i have is keeping the tank warm. i had my 500 watt heater take a dump wile me and the wife where up in the hospital delivering our 2nd daughter and the tank droped to 66 degrees. some of my coral didnt look to good. its winter up here in Wi. now so my basement is cold and the 3 175 watt halides dont jump the tank up in temp to much. most people need chillers to kool the tank, me i need heaters to warm it up

thank you and congradulations, now u can get some more coral
thats why im going to have the refuge drilled i don't want to worry about overflowing and to many pumps to rely on battery backup.

however i think the 10g fuge will have to be a 5.5g. unless anyone knows of a 10g cube tank thats priced rights???

i know i should have drilled it but i knew that i was going to make it bigger so i figured id save the 20 high for something else.
