Quick update (no picts until tomorrow though
)
We picked up a couple more fish.. an indigo dottyback (the hybrid from ORA) and a female green spotted mandarin mate for our male. All fish are getting along famously
I added the lifters to the light over the sump, sectioned off the sump into 3 different sections, 2 for macro algae (chaeto and gracilleria) and 1 for a prop section. I have adjusted the lighting over each section so that the timers and lights are set accordingly (and separately) for prop and fuge. Since we are using T5 lighting, we set the prop section to be a 9" strip across the front of the sump, to take advantage of the lights placed there (one daylight and one actinic). The fuge lights are more towards the center and are 2 6500 K bulbs (or whatever the daylight/sun ones are). My only regret is that I had apparently scratched a portion of the inside front of hte sump wheil scraping algae off much earlier in the setup, and now it obscures the view of some of the frags being housed there. I will have to look into some in-tank acrylic scratch removing kits, I suppose.
Our colored RO/DI lines came in and we replaced all of the clear lines with opaque ones.
We are looking to possibly replace our lighting... while I like the 250W XM 10K lamps, we recently acquired quite a few micros and acans.. none of which look half as good as they did in the tank we got them from. So we wanted to add some actinic "pop" without adding any separate actinic bulbs.
We are looking to go from 250W XM 10k on an HQI ballast to 400W Ushio 14K on an Electronic ballast. Our photo period is currently 9 hours, we will likely be moving to 10 hours within the next mont or so.
Here are the numbers of our current lighting setup :
XM 10k 250W on HQI Ballast
PPFD: 182
CCT: 9921
Amps: 3.27
approx $$ per bulb per month @9 hours: $38
approx $$ per bulb per month @10 hours: $42
And the one we are thinking of moving to :
Ushio 14k 400W on E Ballast (Same as the BLV Nepturion 14K)
PPFD: 152
CCT: 13648
Amps: 3.5
approx $$ per bulb per month @9 hours: $41
approx $$ per bulb per month @10 hours: $45
Other bulbs we are considering :
Giesemann Coral (14.5k) 400W on E Ballast
PPFD: 157
CCT: 11354
Amps: 3.53
approx $$ per bulb per month @9 hours: $41
approx $$ per bulb per month @10 hours: $45
Right now Sanjay is using the 400W Giesemann Coral lamps on IC E ballasts over his tank that is almost the exact same dimensions as our (ours is 6" shorter in length and height than his) and he ran tests with a meter and says that pretty much all of his tank gets more than enough light for SPS. He has a pink milli 4" above the sand bed that has kept it's color and grown nicely (that was one real world example he used to support his findings with the meter)
Since our tank is 24" tall, versus his 30" tall tank, we should be able to enjoy similar results. Both he and we use LA III reflectors that are approx 9 1/2" off the waterline to the bottom of the reflector.
One IC 400W ballast + Ushio 14K 400W lamp will be here from MD tomorrow, at which time we will set it up on one side of our tank to see how it looks and how the corals react. If the test goes well we will order another set for the other side. Since the operating costs are only a couple of $$ per month, it seems like a good option to try (if it had been $30 or so per month per bulb more, then it would not have been worth it.. we have a spreadsheet with our tier 3 per KWH rate, hours of operation, etc that we just plug in the watts, etc fmor Sanjay's site to see the costs per month, etc).
