Aquarium Advice Regular
Ok here's my issue my city water has high nitrates I just finished my fishless cycle on my 60 gallon and today did a 90% water change followed by a 30% with RO water (tested at 10ppm) and added my fish but my nitrate levels are still 40ppm on API freshwater. That led me to test my city water. I did add the recommended dosage of aquarium salt to my tank. Would that kill off Hornwort? I know salt isn't good for plants. I also added 3/4 liter of Matrix in my HOB filter. I'm desperate to find something to lower nitrates any info what may help me would be great. I have a 60 gallon and a 20 gallon set up now and one more 55 gallon begging to be set up also. My RO system only produces 2 gallons per hour so it isn't feasible for me to do that.
