29 gal sw aquarium
I tested my water today and have some concerns. My nitrate level is very high at 100ppm. I did a pwc about 2 weeks ago 1/3 of the water. Replaced the carbon filter cartridge, cleaned sand bed, a general routine cleaning. I have a protein skimmer thats rated for 75gal. My phosphate is at about .5ppm. I don't have an algae problem but I am getting ready for corals. Why are my nitrates so high? How can I lower nitrate and avoid future problems? Calcium is good at 460 ppm and alkalinity is also good at 179 ppm or (10 dKH). ph is 7.8
