Jerry Rickart, a Trout in the Classroom Northeast regional
coordinator, oversees twenty school trout tank projects and says
supplies include the tank (usually 55 gallons), chiller (the most
expensive item), sterilizer, filter, pump, aerator, and of course, trout
eggs, which are usually supplied by the state or local environmental
organization. Supplies a range of level sensors for bulk solid and liquid
materials, as well as aerator pads. The next time
you mow, the cores of soil unearthed by the aerator can be picked up
with the grass and thrown on the compost pile. |
