Well, thanks to everybody for your replies since the last time I posted... I can't believe it's been almost a whole year since I replied to this thread! :bugout:
Anyway, once again the gears are turning and new things are happening... due to neglect and a series of problems that I've just recently been able to get under control, my tank is almost back to square one...
I've lost about 90% of my SPS colonies, which was a real heartbreaker, and almost caused me to get out of the hobby. Fortunately, I'm a glutton for punishment, so rather than take the easy way out, I dove back in headfirst.
I'm currently replacing the lighting I just put in last January with something a bit more energy efficient... using 12kW a day was murder on the electric bill, and that was
just the lighting.
So, I've ordered 4 sets of 36" 39w T5 HO retrofit kits (Sunlight Supply Tek 5) for a total of 8 bulbs... 6 of which will be Actinic Plus (actinic mixed with blue) and 2 11K Aquablue bulbs (a mixture of 60% white and 40% blue).
In addition, I'll be running a single 250w XDE DE HQI bulb in a PFO mini pendant, and driven by an ARO electronic ballast.
What I found most compelling with the new setup was bulb life. T5HO bulbs last in the area of 18 months for Actinics, and 24 months for daylights. Plus, driving the HQI bulb with an electronic ballast should also allow me to get at least 18 months out of it as well. My current bulb replacement costs are around $350/yr, whereas my replacement costs will drop to $250 every 18 months... a very compelling argument for the change.
Combine that with reduced electricity usage (about $300/yr), and it makes id doubly compelling... and from what I've read, T5 HO bulbs have deep penetration through the water column just like a halide, so I shouldn't lose too much intensity (I'll have wait for it to be installed before rendering the verdict however).
This should also reduce heat in my canopy, which will also cut down on how often my chiller kicks on, reducing my electrical usage even further. As an example, it's wintertime, yet my chiller still kicks on a couple of times daily.
I also just ordered a set of CurrentUSA Lunar Lights, and an extra Lunar Link (an additional light module), so that I'll have moon lighting once again. I was so stoked with my first setup, only to have all my LED's burn out within a couple of months. I've discovered that I was shipped the wrong resistors in that instance, which allowed too much current to flow through the LED, which burned them out prematurely... but, rather than chance it again, I spent about $30 for a commercial light setup. I'll report back how well it works once I get it installed.
I've added in some new things to the tank, of which I've started a thread on here:
New Additions - photo intense (dial-up beware!)
My tank looks totally different at the moment, but I've posted a couple of photos of it in this thread here:
Howdy All!
I'll probably post some more photos once the lighting gets here... which should probably be sometime next week for the T5's, and the halide should be here in a couple of days, since it's coming in from Hellolights.
