KNO3
Kevin asked: >>>I keep reading about adding nitrates to a tank and
people suggesting KNO3.
But, what is KNO3 and where can I get it?>>>
KNO3 is potassium nitrate. You may be able to find it at your local
garden shop. A grade of KNO3 suitable for aquarium use is sold as
"Cooke's Stump Remover" According to Neil Frank 1/4 tsp of the stuff
added to 50 gal. of water will contribute 2.9 mg./l K+ and 4.5 mg./l
NO3, respectively. Higher grades of KNO3 are available from chemical
suppliers. One such supplier is Hach at:
