+1 you are on teh right track. I have the eco reefer sand - very clean but the particles are just too small - water always looks like theres a slight fog and i rinsed my sand 3 times before putting it in the tank. Great stuff for a remote sand bed but i wouldnt use it in the display again. The carib sea special grade seems to be the number on recommonded stuff and its sand sifter safe :razz:

I'm thinking 1.5" sandbed with the special grade. Any suggestions. I ran 1.5 on my 75G without issue but it was only setup for 6mnths I'm looking for a long term plan.

1" is enough... dsb is 5"+ so no need to lose vertical room for nothing

That's the depth I was hoping for. I'm not to interested in the DSB. Do you guys still run DSB in your fuge? I see alot of people just run live rock in there fuge and no sand. Also what's the maintenance on a 1" sand bed ? Will sand sifting critters be ok in only 1" ?

yeah they will be fine. you wont be able to get anything that needs a major burrow but if you can sorta pile up the rock so the holes at bottom make for a good burrow.

you can just rake the burrow or get some narrisus and a conch. they push it around alot. Diamond goby will make clean through it as well

I have a diamond goby going over from my 75 to the new tank.
