 nitrate
I have a tank that has been setup for 1.5 years but nitrate stays about 40ppm. Yes I do water changes about 15 to 20 gallons a month.ammonia 0 nitrate 0 Ph 8.4 hardness 425 buffering capacity 300 using mardel test strips.I have a small load on the tank only 5 fish snails crabs ect.Thinking of a sump with refugium or maybe a skimmer would like to build sump from old 55 gal tank with diy plans that I have. What do you guys think?????
