I am having high nitrate issues on a Biocube tank despite dramatically lowering feeding and weekly water changes. I was looking into the Korallin BioDenitrator but the $400 dollar price tag is not doable. Does anyone know a reason why I couldn’t just use the BioDenitrator media with the $50 BRS 5” mini reactor? I suspect the smaller size would be beneficial since I do not want zero nitrate levels. Any ideas?
