Substrate - Help

[andymi]

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

Geo Marine is crushed coral, not sand. You can't make a Deep SAND bed out of crushed coral. Its a sand bed, not a crushed coral bed. The particle sizes of CC are way to big to construct and adequate DSB.
Why can't you take it back? If its unopened, where ever you bought it should be willing to take it back.

HAHAHA, I know what DSB is , just trying to be cheap I guess. It said all sales are final. Maybe the guy will return it since I bought a 150 gallon aquarium from him this weekend as well.
