Re: Aquatic Plants Digest V1 #224
I think I need some help. As I see it, plants need:
LIGHT, CO2, N/P/K, trace elements (Fe, Zn, Co, Mn.....)
I have my tank getting close to the complement of plants I want and still no
bubbles. I have a 2L CO2 reactor which is basically a big bubble of CO2. It
passes about 1-1.5L/day into the water.
The light does not produce bubbles in the plant foliage, even the parts that
are right at the surface and VERY brightly lit.
I tried re-dosing the micronutrients lightly, no cigar.
So I am left with too little N????? Is that likely? The tank has LOTS of fish
and they are pretty heavily fed. I change 25% water about every 10 days. Am I
changing too much? Maybe P or K? Should I take a sample somewhere for a
high precision test? Or????
Please advise. Dave
