Added one pump of easy green. Have been feeding fish a little more to spike nitrates (~3 times a week compared to ~2). Since nitrates have been at zero I am going to try dosing with one additional mid week pump of easy green for a little bit. Still minimal algae growth, if this creates a spike of algae growth over next 3 weeks, I will switch back to once a week. I should note I have lights on in this tank for about 12 hours a day.
