Lighting

As many of you know I had decided to do a restart on my tank and correct earlier mistakes/lack of knowledge from when I started my tank 2 years ago. Several of my corals were dead or dying and I had placed corals into my tank that I later realized was a mistake (Xenia, blue clove polyps, ect...) I looped my pump return from my sump back into my sump again, kept the skimmer running, maintained a constant temperature, maintained choeto in the refugium, and kept the biopellet reactor operational to ...

Well it's me again and again I am having questions about keeping millepora under my lighting. I have had these 4 millepora frags for over a month now and I figured I would slowly acclimate them starting from the bottom up to a higher location in the tank. I have all my brighter colored millepora just under halfway up the tank now but I have a more of a greenish colored one that I can't seem to get off the bottom of the tank. Everytime I moved it up even an inch all of it's polyps retract (I should ...

Currently I am running a 6 bulb t5 setup at 54 watts a piece on a 48' long 75 gallon that hand about 3" above the water.

So as anyone who read my last Blog knows I Recently ordered some new T5 bulbs from ReefGeek.com seeing as I am unable to buy any quality bulbs locally. Placing the order was simple and painless and the pricing was good. Immediately after placing the order I received a phone call from ReefGeek to notify me that 3 of the bulbs I had ordered were not currently in stock and they offered to replace the bulbs ordered with some comparable ones that were actually a more expensive bulb at no extra cost (they ...

I was looking at upgrading to a metal halide/t5 combo that I had found that was within my immediate price range but have decided (since the fixture I was looking at has reports of it catching fire) to try look at the possibility that maybe my current combination of bulbs could be replaced with a more optimal brand/combination. As of right now I am using the coralife actinic and daylights 10,000 in a 50/50 combination. The daylight almost seems overpowering to me and looks almost yellow which I wasn't ...
