Thanks. I am using T5's. 2 TEK Light fixtures. One 6 bulb and one 4 bulb. The bulbs are a combination of Geisemann AquaBlue+, Midday, Actinic +, and Pure Actinic.
Lighting: (1) 48" 6 bulb Tek light, and (1) 48" 4 bulb Tek light.
Cooling: 1 x 9" fan blowing across the surface of the water. 1 x 1/4HP chiller (that never comes on, but is there just in case)
Skimmer: Reef Octopus Pro 250
Return pump: Mag 9
Circulation: 1 x Tunze 6100, 1 x Tunze 6055, 1 x Koralia 5, and recently added 1 x Vortech MP-40 on Reef Crest Random mode.
Supplementation: Aquatic Systems Design 6 x 18 calcium reactor.
Water change schedule: 25 gallons per week using Oceanic sea salt and RO/DI water.
I run no carbon, phosphate media, etc. Only a small piece of filter floss in the sump to catch large debris.
