Welcome to ReeferDude. This site is dedicated to Reefing (keeping live corals), not the other type of reefer :) My 120 gallon reef is pictured above.
My main tank is an all glass 120 gallon (48in x 24in x 24in) with dual overflows. Total system volume is about 150 gallons with the sump and refugium included. I run a Hamilton Belize Sun fixture with 2x 250 watt Phoenix 14k Metal Halides and 2x 54 watt T5 HO for a total of 608 watts. The T5 bulbs are a Giesemann 15k and a Hamilton 03 Actinic. I use a Corallife Super Skimmer 220G with a Danner Magdrive 7 with Fractionating Impeller for protein skimming in the My Reef Creations 36" reef sump with Refugium. A Danner Magdrive 18 is used for the return pump. Two Tunze NanoStream 6055 (1,453 GPH) powerheads are used for additional circulation. The powerheads are attached to a Tunze 7096 controller. The controller is set to pulse mode and creates a nice alternating current. Four Coralife 1 watt blue LEDs are used for nighttime illumination. A Neptune Systems Aquacontroller Jr controls the tank.
I use the Berlin Method for filtration. There is 80 pounds of Fiji Pink Live Sand and about 200 pounds of Live Rock between the main tank and the refugium. The refugium also has a 4" deep sand bed made from Miracle Mud. I have many species of Macroalgae planted in the refugium. The refugium uses a 24" 48 watt T5 HO fixture with 1 10,000k and 1 6,700k bulb. It is on a reverse photoperiod from the tank.
I feed the fish pretty heavily with a mix of Rod's Food, Small Cube Mysis Shrimp and large PE Mysis Shrimp daily. I also feed Cyclopeez and DT's Live Phytoplankton a couple times a week.
I do about a 25% monthly water change and replace the Kent Reef Carbon that I have in a filter bag over the return pump inlet. Both drains empty into one 8" filter sock that is replaced about twice a week and the skimmer is cleaned as needed. I use Salifert pH, KH (Alkalinity), No3 (Nitrate) and Ca (Calcium) tests weekly to monitor water quality and I use Seachem buffers when needed. My Nitrate levels stay around 5 ppm now that the tank has stabalized.
These pictures were taken when the tank was about 5 months old (August 2009). I had a 75 gallon tank for about a year before we switched to this one.
