Has it really been 6 months?

2011-03-28T19:20:00.000-07:00

Has it really been six months since I have posted here? I can't believe it! Well, if you're reading here, you're probably most interested in the LEDS. well, no changes. Same combination, no problems, no failures. However, I mentioned that I was getting into acros. And it's funny to look at these old pics, since these colonies have grown from frags quite well. It's cool to see what time has brought forward. No other equipment, I broke my Liter Meter (dropped it into into water) so I replaced it with a LM 3. I also have a 46g bowfront as astorage tank for my RO/DI water. Nothing else has changed.

New Toys!

Hello! Not many updates this summer. Tank is still rocking along. I have added a number of acropora frags and all are growing well. Heat has not been a problem, despite the warm summer.

I have reduced the total number of bulbs to six. The current setup, from back to front:

470 nm actinic *
22k
16k *
22K
12k *
440 nm actinic

The * indicates it's one of the newer Hi-PAR bulbs. The other three are the older "90 LED per foot" designs.

Other New Toys:

I accidentally water-logged my LiterMeter topoff pump. After 7 years, it is toast. So, I purchased a Bubble Magus. This three-headed monster now doses Calci

um, Alk, and water throughout the day. Any of the single pumps are a little under-powered for the water topoff duties. To compensate, I have made the Alk and calc formulas at half strength and dose double the amount in order to get more water into the system each day.

I also picked up a ProfiLux controller. It acts as a controller for the Tunze flow pump, and its four switched outlets control my moonlights, heater, skimmer, and sump.

Oh: The Tunze 6100 was replaced with a 6105. Slightly smaller and slightly more powerful.

So, will SPS grow under LEDs? Take a look at these fun four photos:

Here's my orange cap in a 130g tank, growing up the front side of the tank:

A closer look of at least an inch of growth up the front glass... it was also attached to the back as well:

And finally, the huge beast, out of the tank prior to surgery with a Dremel and a high performance non-breakable cutting blade:

"Tank of the Month Award"from Captive Reefs!

Wow! The system was given the "Tank of the Month" award by Captive Reefs, a internet forum. Seethe writeup and system details at: http://www.captivereefs.com/forum/showthread.php?t=8095 for all the gory details! :)

April Update... Gen 2 "Hi Power" bulbs

2010-04-28T06:25:00.000-07:00

The tank continues to thrive under the LEDs. Some interesting observations:

The Hi Power bulbs seem to be a LOT more PAR. Some light-hungry SPS corals really colored up when I added the first hi-power bulb (a 470 nm actinic in December). They continue to thrive when I added the another Hi Power gen 2 (16k) last month.

Growth is just sick. I had to perform MAJOR fragging of the "Hollywood Stunner" chalice. The Orange Monti Cap needs to be cut as well. It is now growing up the front and back edges of the tank.

The Hi Powers allowed me to actually drop a bulb. No longer running 8... just 7 bulbs. I would imagine that use of all Hi-Power Gen 2 bulbs would allow reduction to six or -- GASP -- only five bulbs? We'll see as time goes on.

More Cree bulbs added!

2010-03-30T19:01:00.000-07:00

I've swapped out a few bulbs for another of the Cree-based "Hi-Power Gen 2" bulbs.

I played around with the combination in the system; the new bulbs are surely stronger than the old models! It's a new 16k.

So, in summary, running the following:

Hi Power 2nd Gen in 470mm and 16k
2nd Gen in 440mm, 22k x2, and 16k
1st Gen in 12k

Other Tank Hardware...

2009-11-21T19:37:00.000-08:00

This post is about some of the other particulars of my setup. Overall system management is a Reefkeeper 2. I do have the webserver set up so I can monitor the tank from any web browser (it's connected to an old Pentium 3 computer sitting in the basement). I use a Tunze 6100 and a small Korilia nano for flow in the tank. A Maxi-mod 1200 is available as a backup.

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

2009-10-25T20:33:00.000-07:00

Sunbrite replaced my two actinics with the new 2nd Generation bulbs! I also was able to acquire some other 2nd Gen bulbs as well. I hooked them all up on September 18th. A few things about the 2nd gen bulbs: the LED portion looks the same, but the case is thicker, with the back having a silver plastic ridged cover. No longer do the bulbs flex; the structure is much sturdier. Having said this, they no longer look like T8 bulbs quite so much. The tube is also thicker, so I had to open up my brackets a bit. The pic below shows a three 1st Gen bulbs mixed with five 2nd Gen bulbs:

When I installed the two extra 1st gens for more light in the front of the tank, it gave me a total of 8 bulbs. The original six bulbs were Bright.... but adding two more makes the tank REALLY BRIGHT!

Timer Pack...

2009-10-25T19:48:00.001-07:00

I have made one more addition: I installed the Sunbrite "Timer Pack." It's a little box that has the leads hardwired into it for 8 Sunbrite bulbs. It also has separate timer functionality for each bulb. It probably weights about 8 oz at the most, and has a nice looking plastic case. The interface is a PITA... not difficult, just inconsistent, which can be somewhat frustrating. But, once set up, it is pretty sweet. I have it plugged into an "always on" outlet of my ReefKeeper 2, so it really cleans up my wiring situation.

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...

2009-10-25T18:55:00.001-07:00

I have been ultra interested in LED lighting over the last several months. It started at the Lansing frag swap in February 2009, with the display by the PFO people of their latest Soleris system. Alas, it was also their last system, as they are no more. But the concept fascinated me.

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.)
