I haven't posted in a while as my tank is doing quite well and corals are growing phenominally well. Some minor issues with Cyano, but hoping I have the source resolved and it will resolve itself over time. (My hope).
So, now my tank has aged enough that I'm into Equipment woes... If I'd known going into this 6-9 years ago that all the expensive equipment would need replacing every 5-6 years. I might have considered not going large (340 gallon)
I have 5ft Aquatic Life T 5 fixture 4 bulb 80 watt each, setup at maximum width to house 3 AI Hydra 52 Leds facing front to back of the tank. The AL fixture came with brackets to setup LEDS this way for wider tanks.
I have 2 dillemmas -
1. Primary issue is I thought spending more on lights would equal longer longevity e.g. 10+ years of solid performance. No annual bulb changes, less electricity, and longer longevity than T5s or Metal Hallides. I was so wrong...
a. All 3 of my AI Hydras have 2-3 diodes burned out in each of the 3 circles of lights. That's a total of at least 27 diodes burned out between the 3 light fixtures. One of the Fixtures has more than three diodes per circle.
b. I reached out to AI and they now tell me (Evidently marketing materials have changed), that expected life expectancy is around 5-6 years.
c. I have the option of Paying for Shipping to AI and return Shipping from AI, and they will then tell me the estimate to repair the light fixture. (I have no idea if this is $100 per diode - so $600-900 per light) or $10 per diode ($100 per light).
d. If I elect to have them repaired, how long will the working diodes last? Or will they burn out as well in the next year?
2. The second issue is the new LEDs on the market are not tested with the aquatic life fixture. The brackets I have won't work with the new AI Edge LED. There's a possibility I may have to hang any new LEDs separately from the AL fixture I have.
a. In working with AI and AL neither have tested any of the new lights on the market with the Aquatic life fixture.
b. I'm hearing rumors that T5 bulbs are getting hard to come by and may be phased out at some point, rendering my AL fixture useless.
Knowing newer lights on the market are in the $700 range.
Tank is a 340 gallon (Custom) 6 ft by 3ft wide by 31" tall.
I just had the Par Checked with the reduced diodes and brand new T5 bulbs, and at the top of my SPS Par was around 300 and at the bottom at the top of my hammers and other Euphyllia I'm getting around 120 par. Sand bed is around 100 par. Not bad with a 30% reduction in LED Diodes.
My initial thought was to get 1 AI Hydra 68 Edge, figure out how to mount it between my AL fixture. Using the bracket I have for my Hydra 52s and attaching it to the bracket from AI for the edge. Then, Send the 1 AI Hydra 52 in for repair that the edge replaces, and replace one light LED at a time and end up with 4 LEDS fully functional. Reduce the brightness from the 90% I'm currently at to say 70% and retest Par. The cost of shipping one at a time, may not be economical.
A second option is to sell the Hydra 52s as is for cheap: $100-$150 each and bite the bullet and replace all three Leds.
A third option is to wait until the Hydra 52s die further and take no action now before doing anything.. Risk here is Par continuously reduces and corals start to suffer and the shock of a new light could be more extreme and cause disruption to the entire mixed reef.
If it was your money - what would you do?
Picture of my mixed reef for attention.
