White patches (now with pic)

[TammyLiz]

Havin' a problem. I have some orange/green paly polyps that have been doing well since I got them a few months ago. So today I bought some brown/greenpalys. But when I got home and stuck the bag in the tank to float I realized that my orange/green ones now have some white patches on them! I bought some chaeto last week which is the first purchase I have made for this tank in months, so it could have been something introduced with that, maybe?

I just don't get it that I can spend so much time staring into this tank and the one time I am introducing something new I spot something wrong.

I would post a picture but I'm having trouble with my photobucket account. Will do so when I can. The white patches don't look like nodules or bumps, but a spot of white filmy material, or maybe damaged tissue.

Thx, if you can help point me to what it might be. I'm thinking of doing a freshwater dip. I don't have any lugols but could I use kents iodine? I have some of that and lugols is iodine, right?

In the mean time, what should I do with the one I just bought? I'm afraid it might spread to it and I'd rather not lose both...

Got the picture up.

looks like just sand to me.. most protopalys and grandis's take in sand as part of their structure. even some bottom polyps like these.. ( SOMEONE CORRECT ME PLEASE IF IM WRONG ) not close to any zoapox..

 

[TammyLiz]

No, its not sand. It is the circled areas I am talking about. The areas in question do not look grainy. You're right, these polyps do take up sand and you can see it in the picture, but the areas I am talking about are on the top of the polyp and are hazy white looking. Circled in red.

could be too much light, bleaching ????

 

[TammyLiz]

Forgive me for being so new but I thought that bleaching occurred over the entire polyp, not just in spots? So I hadn't considered that.

These polyps, since I acquired them from another hobbiest a few months ago, have made a habit of only half of them being open at a time during most of the day. But a week ago my mushrooms started stretching toward the light and all of the button polyps started opening at once all the time. I am thinking the bulbs likely need to be replaced based on the mushrooms behavior. Could it be that the button polyps were closing up before from too much light and now are open because it is not as bright? I thought they liked bright light, though, and they are under the NC DX lights which are 2 x 18 watt CF.

I am totally grasping at straws because as I said I have no experience to draw from. Only what I've read. It may be that these spots are nothing to worry about but I always like to take care of problems early if I can. There has been no change since I originally posted a few days ago.

If you shroom is stretching, just like zoos then yeah they want more light.

I was just throwing it out there.. but most spotting on zoo's/palys occur during intense lighting schemes... but these are you regular bottompolyps type.. pretty hardy. and grow real fast.. worst case scenario if your very wary of it.. cut off the polyps in question.
