Aquaillumination Aquatic LED Illumination

This 5' LED fixture was ordered December 27, 2007 from ReefGeek. The LED fixture was manufactured by Aquaillumination. I knew they'd be on back order for a few months, but it finally arrived and was installed on March 5th, 2008. And, meanwhile, my corals had finally had enough of the expired 2X 175W Metal Halide, 2X 96W PC bulbs. Their growth was inhibited and some were visibly retracting from their skeletons. I couldn't even keep a Montipora capricornis happy! It was around this time that I decided to concentrate on the water parameters that I previously blogged about on "Pulsing Xenia: The Rebound Story". With the improved water quality and AI LED in operation, coral response has become 100% better.

Other AI Users?

I've noticed that there does not seem to be much discussion about these units on the internet, so I've decided to contribute to the blogosphere by recording my experiences here. One other blogger that I know of can be found here. Maybe I'll impart some vital information to one of the 100's of users out there? As it turns out, I do have one vital piece of information found below. Unfortunately, (okay, the real reason why I'm blogging on this subject) I've got another, new major problem which might just be specific for my device.

VITAL INFORMATION #1

Check the fan units and make sure that they are all working when you have the LED's at high output. Don't assume that the controller will be able to notify you of this type of malfunction.

Fan Trouble Discovered

Toward the end of April, I decided to use my hand to feel the heat being blown away by the 5 pairs of variable speed fans on top of the unit during peak lighting output. I noticed the central pair was not operating at all. I was disappointed to find that the controller was not indicating anything unusual about overheating or fan malfunctioning because the heat sink was really hot. Maybe there wasn't enough overheating to trigger a "CHECK FANS" or "OVERHEATED! See Manual" trouble code as indicated in the online AI Manual? Or maybe the heat sink was doing a good enough job dissipating heat with the help of the neighboring, working fans? Regardless, I contacted AI tech support. They promptly sent out a pair of replacement fans after I was able to show that the problem followed the fans when I swapped positions on the unit with a known working pair.

Fan Replacement

At first, it was hard to figure out how to unhinge the plastic protector from the fans and have it snap back in without feeling like you might break something during the process. The pieces were flexible and strong and I soon became an expert AI technician. I had to power down the entire unit before removing and adding a fan pair. Then, I had to wait until the unit provided enough excess heat to trigger fan operation. The replacement fans still did not work. Another pair was sent to me. I must note here that I could visibly see that the replacement fans' wiring was a lower gauge than the originally installed fans.

Electrician Neighborhood Pal (ENP)

In the meantime, I took the fans to my ENP. With his fancy equipment he was able to determine that the diodes in the leads were installed in an opposite configuration. In other words, all I had to do was plug the fans' red/black leads in the polar opposite direction and they would work. And, because of the design, the fans would still rotate in the proper direction. While we were working with the replacement fans, the wiring on one lead came apart. My ENP seems to think that the soldering wasn't applied correctly.

Fan Summary

My ENP also opined that there could have been a batch of these fans that might have been installed in the production line of these devices. While I have no clue on how the intricacies of the AI production line works, I would still like to bring this issue up for other AI users to investigate. I'm currently on ReefGeek's and AI's mailing list and, besides the usual coupon code announcements, I have not received any other notifications. In addition to Googling, I've also perused the ReefCentral Sponsor Forums where ReefGeek, but not AI, maintains a presence.

The Next BIG Problem
(Why Me on a Friday Night?!)

Yesterday, the power went out on one of my home's circuits. This is basically what happened because no other electronic equipment suffered from any unusual power surge. Nor did the neighborhood complain of anything unusual concerning our electricity. In fact, my ENP happens to keep records of this sort of activity! His report: nothing unusual during that time. Also, our neighborhood power lines are located underground away from lighting strikes.

When the AI LED's were powered back on, they went into a constant flickering mode. After having them powered off and powered back on, they continually cycled into a complete shut down mode. While at work, I sent an e-mail out to AI tech support and by the time I got home, they called me. We were able to troubleshoot and at least get the unit down to 0% White and 50% Blue, but the unit continued to completely shut down. At this point, it seems like the power adapters may not be at fault.

AI tech support decided to send out a replacement circuit board which will arrive on Tuesday. My ENP has volunteered to join me on that occasion. So, my reef tank is headed for 4 days of darkness. My fish are in a perpetual state of being in their Pajamas. I've read about people using several days of darkness to combat algae problems in their tanks with no ill effects on their coral. We shall see.

....UNTIL THEN: SAVE MY REEF!!!
