Adding Nitrate (kno3)

ken6217 · 01-20-2004, 02:05 PM

Can someone answer a testing question as I may have added to much to the tank. I have a Lamotte test kit. I got a reading of 2ppm. The instructions read as follows:

"Record as Nitrate Nitrogen (NO3-N). To convert to nitrate (NO3),
multiply result by 4.4. Record as ppm Nitrate".

So do I have 2ppm Nitrate or 8.8ppm nitrate. If I do have 8.8, is this too much at this point?

Thnaks,
Ken

You have 8.8ppm of nitrate. That lamotte kit tests Nitrogen, not Nitrate, which is why you have to convert it.
8.8 nitrates is almost perfect for a planted tank. Most shoot for 10ppm.

Thanks for your reply. Is it ok to hit the 8.8 over the course of 24 hours? Will it increase my algae even more? I must say that when I was adding smaller amounts at a time I couldn't even get a reading until I basically started adding 10ml at a time at .37ppm per ml. For three does of 7 ml I hadn't even gotten a reading.
What do you think.

Thanks,
Ken
