I got my ferts from the aquariumfertilizer.com today... yay!!! These are what I got 1 pound CSM+B Plantex 2 pounds Magnesium Sulfate 1 pound: Mono Potassium Phosphate 2 Potassium Nitrate I can't wait to mix them all up and start dosing tonight. Question. Can I use tap water to mix those ferts? or I should use distilled, or bottled water to mix them up? Also, should I warm the water up a little bit by putting it into microwave oven before mixing? or the powder can be mixed in cold water without issue? Thanks guys.. I'm so excited.
