This is my first planted tank, and I want to make it a heavily planted one. My tank is 36g and has amazon swords, java fern, java moss, othellia? and other low maintenance plants. I currently have one life-glo Fluorescent Light Bulb 20W 6700k in the tank, and I dose with liquid co2 (excel) every other day, and flourish once a week. My problem is that, i've had my plants for a couple weeks now, and been dosing for that long as well. Some of my plants like my othellia have transparent leaves, and other plants have spots of brown or black on them. I have otos and shrimp for algae care but still have spots. Can anyone help me find out why I have no growth and have transparent leaves. Some plants like my java fern and moss look to be fine though.
