Hi,

I am calling all experts out there to help me with feeding my plants.
I have to admit that my knowledge in this area is very limited, but
I've learned a lot since I started reading about it.

Let me give you my tank stuff
75gal tank
2Xodno 4ft t8
4xodno 4ft t8 (two bulbs total)
404canister with spray bar and an ac300.

Diy co2 currently using three soda pop bottles. The co2 is inserted
thru the inflow of the 404.

Water parameters:
Ph without co2 is around 7.8-8
Kh 180 according to hagen tests

I have all sorts of plants, echinodorus, javea ferns, moss, anubias and
other that I don't even know what they are.

I have bought plant gro spikes 15-3-12 and used some jobes 10-10-6
spikes cut in four.

I noticed some improvements but not what I expected.

I got today an hydroponic fertilizer from plant prod.
It says it is 10-6-16

Total nitrogen 10% (doesn't say anything about urea)
Available phosphoric acid p2o5 6%
Soluble potash k2o 16%
Calcium 7.2%
Magnesium 2.2%
Sulphur 2.9%
Edta chelating agent 1%
Chelated Micronutrients
Iron 0.3000%
Copper 0.0052%
Manganese 0.1042%
Zinc 0.0052%

Also contains boron 0.0157%
Zinc 0.0105%

Directions says to mix 5ml for 5l of warm water.

I would like your opinions on how much dosage should I put in the tank,
if I make a one liter solution using 1ml of the powder without messing
up my tank?

Thanks
