I've put up a black background and set the 13w galaxy light up over the 1.3. It's about 5.5-6.0 inches above the water. The wood has a much nicer brown color under this 7000k light, not at all like the orange hue it had under that other light I held over it for the above pic. I did a Ro water change and added 1/4tsp Equilibrium and a 1ml Excel. I added maybe 1/16 tsp of baking soda. Then I planted a few small cuttings of Pearl Weed to see if anything will grow in here before ordering a lot of HC and sending it to it's doom.
From now on I'll be dosing Excel at a rate of .2ml a day...somehow. At that rate, this 250ml bottle should last me about 3.5 years
So now I just need to dose ferts. I want to try EI @ 25% normal dosage.
So how do I add:
.0023 tsp of Potassium Nitrate
5.682x10(-4) tsp of Mono Potassium Phosphate
.0455 ml of micronutrient solution
Does anyone make 1/500th teaspoons?

Looks like I'll have to mix solutions.
How do you guys dose your carbon enriched nanos?
