Nitrate deficiency, easiest way to raise it?

i have a heavily planted 20 Long, and when i was doing my water tests last night, i noticed that my Nitrate levels were 5 PPM according to my AP nitrate test kit (it's fresh, not expired)

5 PPM seems awflly low for a heavily planted tank, i've read threads detailing how to use potassium nitrate to raise the nitrate levels, but i also have a spare bottle of Miracle Gro liquid, if i keep the dosages low, would it be okay to use this?

Total Nitrogen--8%
1.2 ammoniacal nitrogen
1.2 nitrate nitrogen
5.6 urea nitrogen
available phosphate--7%
soluble potash--6%
iron--0.10%

derived from ammonium phosphate, monopotassium phosphate, potassium nitrate, urea, iron HEDTA

worth trying, or a problem waiting to happen?

Don't use it.

Mainly because the free nitrogen is primarily derived from Urea, which can cause all kinds of stuff to go wrong in your tank (fish health etc). Its similar to what happens if Jobes plant sticks get into the water column.... Heh.. still battling hte algae after that little mishap..

5ppm isn't unusal.. Heavily planted tanks CONSUME Nitrate.. thats why we have to dose it.

I would either invest in some aquarium fertilizer like Tropica Master Gro, or the Seachem Flourish line of Products if you only need to dose a little... But if you find the expense getting too high then you can start looking at making you're own fertilizer base don dry chemicals like Potassium Nitrate etc...

Thats what I have been doing for 2 weeks and it has helped but the pearling is killing me...it looks like a bubble wand is in the tank. I also changed 2 of my bulbs today, the pcs on the front are good but the OD'ed 4 footers were long overdue it seems...I didnt realize just how bad they were and I think this might put me over the edge.
I have been fighting my tank ever since the change...I should have known better.

I just don't understand this seemingly prevaliant attitude. A 250 mL bottle costs $3.99. At the rate I dose, this will last at least a year. How does spending $4 on an aquarium grade made-for-aquarium product make me a rich guy?

Ok, so you are buying it mail order. If I buy it locally it's more like a $8 bottle of product. I have five tanks to dose. A total of 115 gallons. That 250 ml bottle might last me about a month. I can get 50 lbs of KNO3 for under $20. And guess what. That's exactly the same thing that you are getting in the bottle. The difference is I'm not paying for the water in the bottle.

I would not say paying high prices for water in a bottle makes you a rich guy. But it does seem to me that you might have more dollars than sense.

Angry

That reply is really uncalled for - this is supposed to be a friendly forum? Just because I have my own preference doesn't warrant that kind of flame/troll, telling me I have no sense. How is it that you know for a fact that Flourish Nitrogen is the exact same thing as powdered Potassium Nitrate? What is your source?

Hypancistrus,

KNO3 = Potassium Nitrate

Take a look at Seachem's website here:
http://www.seachem.com/products/prod...hNitrogen.html

Take a look at this quote from that page:

Rex Grigg may not always come accross in the most friendly manner but he does know what he is talking about.

Don't read into my reply things I did not say.

And greenfish gave you the link to the Seachem info. I was actually looking at their info when I posted the first reply.

I am a confirmed believer in all info from Rex Grigg!!! A very knowlegable aquascaper!!! Do the cheap and easy way buy KNO3 and some CSM for ferts and save money!!! I did and will never buy water with very little ferts added again!!!

So what should you try to keep your Nitrate levels at anyway?
