Hi
Can someone please tell me what the target nitrate is as I have worked out what I am adding after following this calculator:
http://blog.fluidsensoronline.com/calcu ... ive-index/
My tank is 5'x2'x18", I measure the water depth at 20" excluding substrate so comes to 330 liters water and used it in the online calculator.
I make up 31 g of KNO3 in 1000 g of solution and add 165g on days 1,3 5 so added 15.3 g of KNO3 .
KNO3 is 61% Nitrate.
15.3 x 0.61 x 1000/330 = 28 ppm Nitrate
But that's for the whole 330 litres, I'm only actually dosing the 50% water that I change so its actually 2 x 28ppm = 56ppm nitrate.
I vaguely remember reading years ago that the target was roughly 10-25 ppm and above that it stunts the plants, can someone please double check my calculation and tell me what the target nitrate is?
is it true that too much nitrate stunts plants & fish?
It's just that it looks too much to me, I did a 50% water change about a week ago and I think my plant growth has improved?
