I have this tiny 3g tank that is quite very heavily planted (http://www.plantedtank.net/forums/ta...-lots-pic.html and http://www.aquaticplantcentral.com/f...no-tank-2.html)

since there are no feeding, naturally I will need macro nutrient for the plant to grow. I use seachem nitrogen, and the instruction suggest 2.5ml per 40gallon (2x per week), which means for my tank size, I should dose less than 0.2ml @ 2x per week.

However, i found that extremely inadequate, and the plants show obvious sign of deficiency using the recommended dosage.
So I am wondering what would be a more realistic dosage to ensure the plant get the nutrient they need, but at the same time, safe for the inhabitant (2 shrimps, 1 just started carry eggs :tongue

The instruction said to use the following formula to measure nitrate level -> 0.25vn=m (v= volume of tank in gallon, n= desire nitrogen increase, m=volume of dosage in ml)
What is the ideal nitrate level in a planted plants? (The tank constantly measured 0 nitrate right now)

Thanks for the help!!
