Frank Rossi (2003)
My Plenum reef tank has been up and running for five years. Once in a while I drip a little Kalkwasser to boost the pH. As everybody can see the tank is loaded with fish. Most of the corals came out of my previous 75 gallon system that was running for five years with a Plenum. The soft corals and the large grape coral are about 10 years old.
