Nitrates help Please

On the big system like yours i would go with DeNitrator.

water changes are costly on that saize and would not bring No3 down anyway, because all that junk is stored in live rocks and sand bed.

quote from J&L's site.
Nitrate troubles? Current research shows that sulfur based denitrators hold promise for significant nitrate reduction in heavily bio-loaded systems. These experimental biologically driven de-nitrator/reactors rely on a combination of pure sulfur, aragonite and sulfur reducing bacteria. NO-NO3® is that media.
