update!
found the sand

dry argonite. it comes in 50 lb bags for 50 bucks the guy
thats not a bad price.
said a 40 breeder would prob need 2 bags to get a decent sand bed.
LULZ... 160 lbs gives me 4-5 inches on my 75 gallon.
also im goin with a 4 bulb 36 in t5 fixture and a rio 1400 for the pump.
sounds good on lighting. Only thing I have to say is that rios like to over heat and spill their guts into the aqaurium.
also the lfs store i found yesterday can set up th ecomplete over flow for about 200 with box and bulk heads with a drain and return hole.
do you guys think i should just do a drain hole and have a hang on back return?
That sounds really expensive IMO. I am doing a through the glass return as well, but there is no added benefit from it (im doing it because I made a boo boo....). An over the back return is sufficient.
thats all i got so far.
