The Great 240-Gallon In-Wall Reef Project

Tank - Special ordered glass Oceanic brand 240-gallon Reef-Ready. Two bulkhead holes (for the closed loops) drilled in the back glass at center height and 6" to the center from the sides of the prefilter boxes. All silicone was done in black. The tank measure 8' X 2' X 2' and has 1/2" glass all around.
Lighting - All main tank lighting is contained within the DIY aluminum light box that measures 8" tall X 15" deep X 8' long. Four Hamilton 250-watt Double Ended 14k Kelvin metal halide bulbs in four PFO mini-pendant fixtures and driven by four IceCap 250 electronic ballasts. Eight 46.5" super-actinic URI VHO bulbs on two circuits drive by two IceCap 660 electronic ballasts, one controlled by a Niche Engineering 500 Dimmer to simulate dawn/dusk. Three 25-watt incandescent blue "party" lights as moonlights. One each 150-watt Iwasaki 6500 Kelvin metal halide bulb on both the sump/refugium and grow-out tank, both driven by IceCap 150 electronic ballasts.
Pumps - The main circulation pump is a Sequence 4300 (previously an AmpMaster 3000). The skimmer is driven by an Iwaki MD100RLT. The closed loops are driven by an Iwaki MD55RLT and a MD30RXT. The water change saltwater mixing is done with an Iwaki MD40RT.
Heaters - Four EboJager 250-watt. Two in the sump and one each in the two prefilter boxes.
Chiller - Aqualogic 1/3 horse power drop-in titanium coil type.
Controller - Neptune Systems AquaController II with PH, Temperature and ORP monitoring and control. Aquanotes software is utilized for programming.
Calcium Addition - Calcium reactor is a Knop HD Calcium Reactor with Knop Koralith media. I added a DIY second chamber that measures 4" X 8" X 19". The Kalk-reactor is a DIY converted Top Fathom skimmer that measures 6" in diameter and 19" tall and has an internal MaxiJet 1200 powerhead for mixing.
Phosphate Reactor - DIY reactor chamber with Phosban media. The reactor measures 4" in diameter and is 19" tall.
Sump - Acrylic 55-gallon tank with internal baffles. 75 and 100 micron filter socks on tank returns.
Skimmer - DIY acrylic, dual Beckett injector that measures 4' tall. The main contact chamber is 10" in diameter. The output is through a 2" gate valve and lines.
Reverse Osmosis Water Filter - SpectraPure 50-gallon per day with a 90-gallon per day piggyback. There are two Deionization post filters in addition to the sediment and carbon prefilters.
RO/DI Water Reservoir - 25-gallon TruVu acrylic tank with a DIY automatic refill mechanism of my own design.
Mechanical Filter - OceanClear 75-micron canister filter run occasionally.
Chemicals - ESV brand calcium hydroxide, magnesium and carbon. Marineland brand carbon. Oceanic brand synthetic salt mix.

This chart shows the power consumption of each piece of equipment at any given moment. I acquired these figures utilizing a Kill-A-Watt meter attached to each unit under normal operating conditions. They are listed in no particular order.
