Acro bleaching!

[fishmanstan]

HELP!
I got a ice fire echinata frag off eBay and it was great for about a week. A couple days ago I looked and saw a lot of the blue tips gone and the brownish base color changed to white. Yesterday I saw one of my purple acros w/green polyps do the same. I know it is bleaching, since I have not seen any tissue being thrown off (RTN). I think I may have another frag bleaching as well...what do I do?
I have Radion gen 2s and got them Christmas eve. I am up to 40% and was at 36 or 37% like a week ago, and I have been trampling it up slowly since I started at 30%. What can I do? I put the ice fire in the sandbed and lowered the purple and green acro a little bit. I run my lights from 10AM-6PM.
Thanks

Check your alkalinity first then other parameters and post it here. It's hard to say. It could be combination of factors.

Ok. I will later.

Once you have eliminated chemistry and pest issues so your confidant it's a lighting issue cut back on photo period or percentage until they get acclimated. What kind of lighting you had before can really make a difference. For instance if you came from some tired old T5 bulbs and popped on the radions it could be a real shocker to the corals. Just back off some and go a little slower to allow them to acclimate.

Do you have a way to takes a pic of this "bleaching" ? How do you maintain params? Whats the rate of fluctuation?

 

[fishmanstan]

Idk how to post pics. The ice fire is all white, and the purple acro has a tiny bnitof purple and polyp extension on the very bottom.
I do WC's every two weeks, and will be doing one this weekend on Saturday or Sunday.
I'm not sure on the rate of fluctuation..

what is your method of topping off make up water?
Islander84- I have the same set up as you, 144g half circle, and recently upgraded to the phoenix 14k the par is soo good i have to run them on 175w for a while until my corals acclimate to it.

 

[fishmanstan]

? I use RO water I'd that's what ur asking..

 

[fishmanstan]

Well I moved both acros to the top again. The purple and green acro is regaining its purple from the bottom up, but the ice fire is still completely white..doing a WC later today.
