nitrate source? anything I might have handy?
I know I can order nitrate fertilizers online, but I was wondering if there is a common chemical laying around my house, or that I can pick up at Home depot that I can use.
I have a ton of greg watson's PMDD mix and a half dozen other things, but it is a shrimp tank and I am concerned that the micros are going to kill my shrimp- I definitely have a nutrient imbalance evidenced by stunted growth and I dose pmdd's at 3x recommended strength and still can't keep nitrates up in this tank, but the phosphates seem high (1ppm) so I am looking for straight nitrate...
