Other Tank Hardware...
The sump is pictured at right; I just added a larger model last week after using a smaller Pro-Clear since the tank's 2005 start up. Skimmer is a Tunze 9010.... compact, energy efficient, easy to clean, and quiet. Heater also rests in the sump.
The thin white tube feeds topoff water from the basement.
Return pump is an Iwaki MD-30. The smaller Iwaki pumps are quiet (no fan), cool, and use relatively low energy. You can see the Sunbrite timer pack under the tank as well.
Topoff water comes from an old 15 gallon tank sitting on an use d aquarium stand. I manually fill the tank every week or so with RO; it's mixed with a Sodium carbonate and/or sodium bicarbonate to maintain the tank's alkalinity and PH. A SpectraPure "Liter Meter" doses the water upstairs to the sump.
Finally, the RO system. An electronic valve (upper left) is turned on for 2 hours daily by a timer (at right). The valve feeds water to the RO system (middle left), which flows to the Rubbermaid container. This water is used for making up water for topoff and weekly changes.

2nd Gen Bulbs
Timer Pack...
The cool part is creating a dawn to dusk transition. I start the day with turning on an actinic 440, then a 470... I proceed by adding the 22k bulbs, one every 20 to 30 minutes, then progressing to the 16K bulbs, and finally the 12K daylights. At night, I reverse the sequence.
Setting Up the LED system...
Came to research quite a bit.... and learned that industry minds are starting to turn as well. Reef lighting guru Tullio del Aquilla recently stated that LED lighting is good enough now to claim that all other actinics are obsolete... and that the next generation of lights will start giving T5 and MH serious challenges.
Most designers (and DIYers) have focused on the larger 5 watt LEDs, like the Cree, and placing them in panels (like a Soleris). I have taken a leap with a company offering a "bulb" that uses smaller LEDs... 90 per foot, in fact, and installs them inside a T8 "bulb." Really, it's an unbreakable plastic case! So, I'll have 3500 LEDs over my tank: 6 foot bulb x 90 LEDs per foot x 6 bulbs! No ballasts are required.... just a clip over each end (uses the same type of ends that you would see on a T8 bulb) and the wires go straight to the outlet!
The following pic gives you a sense of the color spectrum. I have started my system with a 12k, a 16k, two 22k, and a pair of actinics (440mm and 470mm).
Each bulbs uses a minuscule 28w!! For those counting electrical use, I have cut $35 to $40 per month from my electric bill over my halide system (2x 250w and 1x 175 magnetic ballast, plus 2x96w PC actinic).
The bulbs come with wire clips... again, pictured. Very simple... lamp cord, which plugs directly into the wall. NO Ballasts!!!!
My mounting is somewhat a cheesy DIY effort.... simple but effective! I picked up some scrap molding from Home depot, drilled 1 1/4" holes, and mounted them to my canopy. Inset bulbs, and we have liftoff.
(p.s. -- the two clear 18" tubes are ebay moonlites.)
