Sorry, my mistake - it is 85W Total - here's the link - http://shop.stevesleds.com/Nanocube-28-LED-Light-System-NC28RF.htm

That sounds like the issue. After the 8 week acclimation period, most people end up with the blue channel running at around 90%, and the white channel is around 60%-90%. Sounds like your corals are starving for light.
To determine how much light to provide your corals with, it is very important to watch your corals and their response to the LED light. Start off at less than half dimmed down, and see how the polyps respond after 5 days. If the polyps are balloon like and relatively clear, they need more light. If they are small and dark, they are getting too much light. If they are pure white, they likely have been bleached (blasted with too much light), and will take about 3 months to recover using a 30-40% light level. If they appear to be relatively normal, just let them adjust to the LED spectrum for another 3-5 days. After that, increase the intensity of the LEDs approx. 2-3% once every 3-4 days (or 1% every day) over the course of the next 2 months. If you rush this process, it is highly probably that you will bleach and could even kill your corals. Corals will take a minimum of 6 weeks to acclimate and adjust to the new brighter LED light after you have completed acclimating them. During this time their colors will enhance and sometimes change as they adapt. Sometimes browns will turn to blues, sometimes blues will turn to greens, etc. Every individual coral is somewhat unique and as it adapts its colors may change. When introducing new corals, you must restart this acclimation process, by bringing the light intensity down to less than half.
I was adding 1% per week, but backed off of that because I had a Favia that was on the sand, bleach out. It's now back to normal. I was going to try to start increasing by 1% per MONTH increments.
I find Steve's reply interesting - I seriously doubt I could get to 90% on either without freaking something out - either corals or fish.
But on the other hand, the ratio of 90% blue to 60% white sounds like that might be something to try to keep balanced, while increasing intensity. That's a 3:2 blue:white ratio. As of right now, I'm at 40% blue 25% white, which would mean I'm a little heavy on the blue. To keep a 3:2 balance, I should drop the blues down to 37%.
BTW - I managed to keep the JBJ moonlights in tact when I did the Steve's upgrade. I had to move one of the JBJ moonlights because of the new fan placement, but I got them to work.
I haven't been able to find anything on this yet, but half of my light went out this week and I don't know why. Any help you guys can offer would be great. The light is 4-5 years old and I'm just wondering if half of it went bad or what.
Hi Everyone,
I hava bought a 2 year old JBJ 28 Gallon Nano HQI tank , and the /transformer power cord for the moonlight leds was missing. Can any of you tell me the specifications of the transformer so that I can check if I can find one that is cheaper than buying the JBJ replacement one?
3V DC - 380mA is what is on my moonlights now. Nothing special about the transformer block at all - just find something that matches the plug.
Thanks pokerman. I have bought a 3V transformer from amazon, but it didn't work. I have even showed it to few electricians, and they were no help either. I guess the problem was the mA. I will try to find one that matches that too. Also, the issue might be with leds.
Thanks again.
I have had the 28 led pro for about a year. The guy I bought it from had disconnected 2 of the light strips because he thought the lighting was to strong. I want to go in and replace some of the leads with royal blues and reconnect the strips. All the screws holding the clear shield in place are corroded. I've tried to find replacements online but haven't seen any. Does anyone know where I can find them or what size they are to get a comparable at a hardware store? Does anyone have any tricks to prevent the corrosion?
