I have a rainbow torch coral that recently turned white. The tentacles are still extended and you can still see some of the other colors in it but it is mostly white. I am running stock lighting on my bio cube and the parameters are

Ammonia- 0
Nitrite - 0
Nitrate - 0
Phosphate- 0
Calcium - 420
Alkalinity -10
Salinity - 1.026
PH- 8.0

I also have another torch coral but that one is doing just fine.

bleaching?? torch placement?

white as in see through? when my hammers bleached from too much light, it turned see through. I lowered it to the sandbed and it recovered in a month

Mine has been in the sand bed for three or two months in the same spot I have had it since I got him :/

Clownfish how often do you feed your torch? I would start feeding him/her more.

I feed him twice a week. I will try that Barry :)

It's lost its zooxanthellae---the internal elements that let it photosynthesize. Try feeding it. If any survive, it may try to recover. It may have had too little light. It may have been exposed to too much light. I don't know your lighting system---thank you for providing that info---but I somewhat suspect the light may not be strong enough to reach the bottom. Move it a few inches upward, no higher, see if you can feed it---powdered krill (crush some dried) or the like might help. Cyclopeeze if you can get any. Your parameters are all right for this coral. There IS a zooxanthellae replacement tonic---I'm currently testing it myself, but so far no outstanding improvement, after 2 weeks since dosing. The other coral---is it at the same level in the tank, same lighting? Same age?

Yeah the other coral is the same size but has kept all of its color.

The problem piece may require more light. I wish I had more info on the light for you. I keep hammer (a relative) about 12" down from a 250 watt 10,000 k metal halide, and it's nicely colored and extended. I've not seen this rainbow type. What's your k rating on the lights?

Stock Biocube lighting is compact t5's 2 bulbs, one actinic @ 35 watts(420 nm), and 1 10k white. Should be plenty of light for the torch.

Thank you homer :) it's so weird because I got both torches at the same time but one is all white

No problem clown. Just happen to be up as I could finally snap a pic of what I believe to be a stomatella snail, and watching hockey. It's odd that one is fine, and the other isn't. Have you tried moving it around the tank, maybe it doesn't like where it is. As odd as it sounds, my frogspawn starting to loose some color until I found its "happy place".
