Thanks all,
The tank is 300 gallons. It has been in operation for 3 years. I do not run a skimmer on this tank anymore, nor do I use a Calcium Reactor. My maintenace consist of 50 gallon water change every two months with Reef Crystals salt which maintains my calcium level at 400 ppm and allows fast growth of corals, and harvesting of macro algae to remove toxins in the water. No sand bed in the tank - bare. I do have a 4 inch sand filter under the tank. I only have three fish in the tank, a yellow tank, maroon clown, and cinn. clown. Lighting consist of one 400 watt MH 20K Radium bulb. Only one so I can have low-light corals on either end. My philosophy is to have patience and lots of it, not overload a tank with fish, no deep sand bed in the tank, lots of corals and water changes!
