My dry ferts just got here, ive order KH2PO4,KNO3,K2SO4. Im looking all over the forums to find a way to mix the ferts but its a different answer everywhere. Some say just to put the power directly in the aquarium, others say to get a 500 ml container and mix it with tap water. Im a little bit lost. I will be getting today a measuring cup. My tank is a 29 gal, and i have 130watts of light. But at the moment im turning on one bulb which is 65 watts. Also have DIY Co2. I currently have some hair algae on my anubia, some brown algae on tank walls and some black/brown leaves. I will like to do the EI method. Any help would be great.
