Hello! 120G reef tank about 9 months old. Fairly light bio-load (7 fish) but nitrates seem to hover 15-20ppm range with 20% weekly water changes. I realize that this isn't overly high, but would like to add more fish etc but concerned about nitrates / phosphates increasing.
Was going to add Seachem Matrix in the sump to reduce NO3 as it seems a fairly natural and stable way of managing nitrates. But would appreciate thoughts / experiences from others. Thanks in advance.
