great insight / info baby,
thank you for that response. rstagall, sorry this is such an old thread. unfortunately the pure actinic, caused alot of coralline growth also and ive since than have switched to all mhs. ive also moved towards dev. clownfish and away from coralss/ zoos.

I went to a frag store and EVERYTHING was powered by actinic (T5 i believe). It hurt my eyes to be looking at the goods...it was so blue.
They had carpets of zoos growing like weeds in their tanks too...on the sand, glass, in the overflow box! Dana |

So, is it factual that all actinic lights increase growth and multiplication of zoas?

I've done a lot of scuba diving in tropical locales. It is true that sunlight is getting filtered and by the time you get near 120+ feet deep the light left over is mostly blue, but in the first 60-70 feet in clear water there is still lots of "white" light landing on the corals.
Understand that it is the amount of water that determines the level of light filtering. If you are looking off into the distance underwater (the background) the water is always blue because the light is filtered coming down from the surface, and also back to you, or off into the distance. For example, if you are 50 feet deep and looking at something 50 feet away that is 100 feet of light filtering. If you are looking at something that is only 2 feet away that is 52 feet of light filtering. Here are some photos. http://www.usvh.com/photos.html http://www.usvh.com/lightsphotos.html I have noticed that light levels in some reef tanks exceeds the light levels I see in many areas where coral health is very good although corals (and clownfish anenomes) that like to live less than 10 feet deep would see higher light levels than we could put over a reef tank. Just ballpark, but I use 4x90watt VHO's in a 90g tank and see light levels that are very close to what I usually see more than 10 feet deep on a reef. For the fish, I see Flame Angels living in Hawaii at 60-80 feet where light levels are much lower than we often have over our tanks. They obviously prefer this. As someone said, overall health of all of the animals in the tank is important so light needs of individual animals may need to be compromised to suit the overall needs. |

A few things:
I live on a subtropical island and there are zoos growing all over the place. Most of them are in 10 feet of water or less, with the mass majority being in less than 5 feet. There is a coral propagation farm here on Okinawa and they keep all of their zoos under pure actinics and have unbelievable growth. I'm not sure, but I think I might do some tests myself. |

dasank,
thank you for that response. if a jap. farm is using actinics only. that makes me feel even more assured. for the time frame that i had my zoos under actinics, they were always open and had the best growth ive ever experienced since ive been keeping zoos. if my concentration was still with zoos, i def. would still have them under actinics.

Are these actinics the 420's or 450's ?

I'm afraid Okinawa is still growing like that too. It's changing all the time.

It's funny because today I started to experiment with all actinics in my tank before I even read this thread! I have one 96 watt 420 nm and another 96 watt 420/460 nm.
all the blue kinda hurts my eyes, but all my shrooms/ and the 7 zoanthid polyps that i have are bright florescent looking. they're pretty! If they start to look bad then i'll change to 10,000k but I figure if they look better and grow better then how can you say it's unhealthy for them? anyway i'll keep ya'll posted

I tried this for several months and the end results were less than spectacular.
Most of the corals started off doing much better or so it appeared during a short time period. After a few months they actually began to shrink and or lose some of there coloring. This appeared mostly and firstly from the mushrooms and then even a few of the zoas. What I've since done that appears to work even better is to shorten my lighting cycle to 5 hours per day. Not only do the inverts get bigger but they're multiplying at the fastest rate I've ever seen. The idea behind this came from an alage outbreak that I didn't feel like trying to keep up with through cut back maintenance. What's since happened is, my mushrooms have at least doubled in size in less than a month and multiplied. Same for zoas as well as hydnophora and my plate type corals. Theoretically it goes along with normal growth in animals and plants that the greatest growth periods occure during sleep . |

The lighting used is 10,000k (2) 110 watt vho bulbs, 420 nm 110 watt actinic vho(1), Super actinic R 110 watt vho.
Using exclusively actinic did exactly what I thought it would over a long time period. Even though most of the light appearing in depper water seems to be mostly blue, there is also a mixture of some higher and lower par that is included as well and necessary. |

thanks wds! so instead of having a 12 hr light cycle, you have it at 5 hrs? I'd never get to see my corals. Do you only have shrooms and zoo's? I'm not sure if my xenia will florish under a 5hr cycle. It makes sense to me that they grow more if they get to "sleep" more.

the good thing is that there are hobbyist, like you guys are willing to push the hobby beyond its current borders. that alone is success, regardless of the conclusion to this thread.

Yes lil, the timing is set to run for only 5 hours in a 24 hour day. Since the main purpose here is growth and overall aesthetics, I've had better results using a shorter lighting duration which appears in both growth and coloring.
No, zoas and mushrooms are not my only corals either. I've got a fluorescent green hydnophoria (including some frags), a scroll coral, some fire coral frags, a blue/green table top coral, and a sandal brown digitata. Everything is responding noticeably, especially the hydnophoria. The zoas actually seem to have better coloring also as well as the mushrooms which were slowly becoming bleached with a longer duration lighting period. |

this is very interesting. im following along and also thinking about trying it myself. i love how the zoa's look under the actinic lighting.

Hmm 3 days seems a little long for my taste and probably for my animals as well. One day perhaps, but 3 is too much.
Another important point is having optimal life bulbs rather than trying to eek out a few extra months on bulbs or tubes that are already spent. You'll be able to see the difference in many of your corals as the light intensity begins to deminish. Scroll corals especially. |
