CO2 and macronutrients - need guidance
Where is good source to buy macronutrients for a tank with pressurized CO2?
What is the best "format" for the macronutrients? Liquids, powders, granular, etc?
I'm taking the plunge to pressurized CO2 on one tank. I have the set-up ready to go, I just need to have my 10lb CO2 tank filled. I'm comfortable with the hardware aspect of CO2, it's the ferts that worry me! I'll be dosing with Flourish comprehensive for micronutrients and plan on using the EI dosing method, assuming I can get the macronutrient dosing figured out! I'm starting out very conservative on the CO2 levels - I'm actually starting the CO2 in a planted tank w/o fish until I get more comfortable with it.
Light levels will be in the medium to low range, anywhere from 20-40 micromoles of PAR at the substrate, depending on the exact spot in the tank that's being measured.
