I have 2 different sizes of substrate in my reef. I have some sugar sized stuff and I also have some bigger stuff, not sure what size. It is like one step higher than the sand stuff. My question is will I get good denitrification with this substrate still if the smaller stuff goes down to the bottom? I have about 60 lbs of sugar sized and 25 lbs of the other size. It is a 30 gallon. It gives me about 3-4 inches all around. Also I have about 4 inches down in my sump in a 12 by 12 inch area that is mostly the small stuff. I have about 40 lbs of live rock.
, live rock and macroalgae are mainly my only filtration. Can get pics if needed
Will my sandbed be alright?????
