Doug , I am not doing the whole tank with ug,but only one half with sorta crushed coral dead frags about
2-3 inches. The rest of the tank with 1-6inch( Depth)suger sized sand. And i have about 120pounds of live
rock. I have read a lot about the pro and cons of
Dsb, ssb,lr,and ug.i just tring a little of it all.
A couple of things i have noticed is a huge critter population and all my levels have been the
norm. But time will tell.
Who knows what is the perfect setup.A new fad keeps changes(it seems weekly).The
fish and reef stores sure love them
