Ok im setting up a frag tank 48x24x24 with mainly zoa and paly. some sps I would keep near the top. I have an 8x54w ATI sunpower fixture. I also have two 48inch 454 led strips that r 30watts each. will be mounted in front and back of ati fixture.
1. What would be the best combo of bulbs?
2. What duration would u run the 2 channels?
3. What 2 bulbs would u put in the 2 bulb channel?
I was thinking 5 blue plus and 3 coral plus
Or
5 blue plus, 2 coral plus, 1 purple plus.
What do u guys think?
With a frag tank I would be more concerned with growth than color. So in that case I would go with only 2 coral plus bulbs and the other 6 bulbs would be Blue Plus bulbs. However noting that the only corals your thinking of keeping are Zoa's and Paly's I have had better luck with these corals onder much less light than you will getting. So you want to iether put a screen between the tank and the light or position the light fairly high above the tank.
If you want to go brighter than the two coral plus bulbs then a combo of an Aqua Blue Special and a Coral plus will make things even brighter, and you will still have 6 Blue Plus bulbs for super growth.
For timing under ideal conditions you would run the 2 bulbs for 12 hours. This would assure a 50/50 light dark cycle which is the best for coral growth. A simple pair of Blue Plus bulbs is what most people run for this sysle however a few prefer a combo a bit pinker with a sipurple plus and blue plus.
As far as the timing on the other bulbs this is very touchy as different corals especialy in the zoa family have different lighting needs. Satrt with a 6 hour cycle and watch the corals closely. If you see brownng shorten the cycle, it hou need more coral growth increase the time.
Note I'm not running an ATI fixture but with 8 tubes on a 120 gallon I'm running the mid days now down to 4 1/2 hours and have not seen any decrease in growth but have noticed better color than when my period was longer.
