Hi I do a ten gallon water change every week on my 75 gallon tank. I use RO
water and I test to water before adding it to the tank. Ever since I added my huma, my nitrate levels have spiked to 20 ppm
from 10 ppm
. I was wondering if there is anything I can do to get my nitrates back to more comfortable levels. All of my other water parameters are good. My tank is only 3 months old. I was feeding the fish 3 times a day now I am only feeding them twice a day. I also have a maroon clownfish and two yellowtail damsels. Basically am I getting into dangerous territory with my nitrate levels?
