I wish I had 10ppm of nitrates in the tank
. Thats a great reading IMO. I get 20ppm out of the tap/well. Average 40ppm in the tanks, which are all hi-tech planted. I agree too that even liquid nitrate kits are really useless. Anything about 20ppm is a guess IMO. I only know the tap water is 20ppm because we have it lab tested once a year. I use to dose full EI ferts which threw the nitrate really high 40-80ppm. I've since cut the KNO3 from what I dose.
I don't have any health issues w/ fish, but I can't hatch any fish eggs for the life of me. Dunno if its the hard water/nitrate/too much light ect... They all go cloudy on me.
