Trout Update

Students are becoming experts at monitoring tank water quality. They are measuring pH, ammonia, nitrates and nitrites daily, and we are averaging 5 gallons of water change daily. We use a siphon for water changes. The siphon helps to stir up the sediment in the gravel and is a very easy way to remove the water. We removed the bag from the outside of the filter, and are hoping that this will help to reduce the amount of sediment in the gravel. We are still losing 4-6 fish each day, and hope this changes soon. At last count, students estimated there were 89 trout.
