I have a 15 gallon, flourite substrate, 1.5-2 watt/gallon tank. My question has to do with ferts to be added. To assure healthy plant growth FIRST, I would like to use ferts and Flourish Excel to assist plant growth, even water changes, if necessary. What would be the proper amount of potassium nitrate and phosphate to be added to the tank? And what amount (mls) and times a week should Excel be added? Is it better to add ferts 2x a week, or 3x? Does this added frequency (3x) require additional Excel, and if so, how much? What about the addition of micros, CSM+B (1tsp/167mls)- should this be added, and at what frequency? Would a periodic water change be required, and if so, what frequency and quantity would be needed? After using EI, and experiencing the fantastic plant growth, I'm a little hesitant now to underdose, and bring on algae, etc. I would rather put in a little more nutrients and work initially than have to combat algae due to poor plant growth. :gw
