Yes Carissa you are raeding correctly 74 watts over this 10 gal and on for about 9 hrs a day. So I ajusted my ferts to this after VaughnH post nitrate 7 ml=7.56 ppm, phosphate 3 ml=1.59ppm, potassium 1\8 tsp barr's gh booster 1\4 tsp (after water change), plantex 2 ml, iron 2 ml=0.2 ppm all is being dosed daily except gh booster. I am still seeing hair\thread algea, and gda. I have noticed an increase in plant growth the last week. I also added some hydrogen peroxide twice add noticed a decrease in hair|thread alge. Would the dosage of iron be a bit much? A decrease in lighting either in wattage or hrs a day I would guess would help also. If anyone has any suggestions I would love to hear them. Thanks for all the help so far.
