Checked water quality today, and nitrite is up 0.75 ppm, but all else has remained the same. Cleaned filters and changed a gallon of water today. Fish look good, very alert, and a few look like they are in full smolt, their parr marks have almost completely vanished, a vast majority of the fish, however, are still retaining their parr marks. Parr marks may all be gone by next week; could be Monday but it will more likely be Thursday or Friday. They could potentially be released any time between this coming Monday (April 12th) and the following Monday (April 19th). Fish were fed at 11:00am, 3:30pm, 5:30pm and 8:00pm.
