My goal is to reduce the nitrate levels, which are currently extremely high at 50 ppm.
I have been using NO3PO4-X for two weeks, but despite this, the nitrate levels have not decreased, although the phosphate levels are now zero.
My sump is filled with chaetomorpha algae, but they do not seem to effectively reduce the nitrates.
How can I effectively lower the nitrate levels without disturbing the phosphate balance too much?
