Substrate

All,
I was going to use a UGF system with Geo Marine (Carib-Sea) as substrate but have decided to try a DSB for my FO tank.
The tank is a 150 gallon tank and I have 120lbs of this Geo Marine that I unfortunately cannot take back. Do you think it would be ok to mix the 90 or 120 lbs of the geo marine with maybe 100lbs of finer sand like the aragalive or southdown grains? Would this be sufficient to still preserve a true DSB?
Please advise as I want to get the sand tonight so I can put it in the tank :)
Thanks,
Andy
