 Topic: Zoo's and MH's Question.
Posted: December 01 2009 at 8:00am |
|
On my frag tank, I have noticed over the past month or so that my zoo's "stem" has gotten longer. Typically when you look at zoo's they are basically a relatively flat mat, with the heads nice and tightly together. However, a bunch of mine now have stems that are about 1/2-3/4" long. It almost looks like they are trying to get closer to the light (I'm at work or I would just post a picture instead of trying to explain)
I am just wondering, if this is caused by my bulbs already getting old or if I need to upgrade my lighting system. I currently am running 2 x Hamilton 150w MH's pendants with Reeflux 12000k's DE. The pendants are about 4 inches off the surface of the water and my frag tank is only 12" deep. I have only had these bulbs for about 6 months, but I guess they could have already lost their effectiveness. I have SPS and LPS on one side and Softies and zoo's on the other. All are growing nicely, but only the zoo's look weird to me.
So I guess the point of this post is: has anyone experienced this before and would this be caused by not enough usable light?

my zoo's get a longer stem if they are shaded, so I would say yes they are reaching for the light.
another think I have noticed is some zoo's I have in a lower flow part of the tank have longer stems and longer fringe lashes, than the same kind I have on the other side of the tank that is getting alot of flow. So it could be flow to.

I'd like to wait and see the pic, both of the entire tank and the zoos alone.

I agree with Snoyce. They are stretching for the light.

I'm prety sure you need a nice T5 setup over your frag tank too Keith (then when your wife leaves you and takes everything you own, we can all get some of your killer stuff for cheap) lol

If they are stretching for the light, any guess on if new bulbs would help or if a new fixture is needed. the zoo's are only about 8-10" inches below the light, so I would think that the 150's would be bright enough. Strange.

I would sure think that was plenty of light. How is your alk and iodine?

Well, I havent tested for iodine in a little while but my alk is solid at 12.2dkh. However, my zoo's in my display are perfectly fine (system is connected)

It doesn't throw up any red flags for me but pics will help.
Zoanthids also stretch when they are crowded, like trees in a dense grove growing taller and slimmer. The answer in that case is to make more frags.  |

Well they are crowed down there. I was going to have a frag day here soon. I will post a picture after I get off work. However, if this statement is true (which I have no reason to think otherwise), then I would say this is my problem. I think there is a decent picture of the tank in this link. However, at my work photobucket is blocked and I cant remember exactly what picture I used in this. http://www.utahreefs.com/forum/forum_posts.asp?TID=36237

I have some gorilla nipples that have started doing the same thing. They are growing below a Monti Cap that has started to shade them and the stalk on some of them has lengthened to about 3/4". The ones that get direct light look normal.

In my tank I used to have a zoo rock that was flat and horizontal (almost) to the water surface and was only 14-18" from 250W MH. The stems were up to over 1" on some of them so I think it has to do with something more than just light. They were very crowded so that could have been it.

Well, I am 90% positive I found out the problem. I happened to have an extra set of new bulbs laying around which are Hamilton 14000k's. Because the bulbs are a lot more blue the the Reeflux, it made the issue quite noticeable. Here is a (terrible) picture of the tank. As you can see, the right hand side of the is darker then the left. If I switch the wires from the ballast, the darkness switches to the other side. So I guess this means it's time to find new ballasts for my lights.

Yes those frags on the right look horrible. You better put them in my tank until they recover. Then I will give them back. I promise

get the glass on your lights cleaned off really well and replace the bulbs. that tank looks really "shaded" to me which means your glass is either really dirty or the bulbs are old/crappy :) My frag tank had always looked really bright. Yours appears to be dim.
