Hello everyone, my wife and I have been in saltwater for about 29 years. When we moved up to a reef tank our first filter was built from the description in the FAMA magazine, and we have been hook ever since. During the mid nineties we moved all our tanks to a greenhouse, and it has been a learning experience everyday. Our current system is 410 gallons consisting of 4 tanks, sump, and refrugium and will be adding another 100 gallon tank in the next few weeks.
