Bleaching anemone?

[kevstaa]

Hello I’m not sure if this posted the first time but I’ve these rbta for about 4 months now and they’re doing doing but I decided to switch my lights from this https://a.co/d/j7dbQBh to the radion xr-15 blue. Within about 4 days I noticed 2 starting to become translucent. I also didn’t acclimate them to the new light ( which I read you’re supposed to do) so I was wondering what I should do. Should I switch back to my old light or is that too late? Any help would be appreciated. Thanks

Do you have any PAR readings? (Even before and after lux readings will work.) There's other variables that are involved in bleaching. What are nitrate and phosphate numbers? Are you dosing any labile DOC (carbon dosing).

Hi thanks for responding. I just measured the par they are currently at and it’s about 150par . I got kinda worried so I put the original lights back on but when I had the radion (for the 3 days they were on) the par was about 180. I also just tested my nitrates and phosphates.
Nitrate- 5ppm
Po4- 0

Undetectable PO4 is problem and can bleach corals. Feed your fish more. Here's a couple links to check out:

What is your N/P ratio?

I do not think it is desirable or even sensible for reefers to think of nutrient target levels as ratios. It just serves to lead to false conclusions. It is never wrong, and usually far more informative to discuss the absolute levels of each. For example, does it make any sense if N is very...

So as of right now I feed my fish once, every other day. should I just feed more and test my water everyday to see how much food I should be feeding? Thanks for your help

Can u turn the lights down. Or move it in less light

I actually switched back to the lights they were originally under. It seems like they have stopped getting worse but they haven’t gotten much better. Still translucent, just not as much. so maybe the light switch was the main issue . My lights are running
0% white
55% blue
55%royal blue
55% violet
No reds or green (not sure if this matters) about 150 par
I also forgot to mention that the 2 anemones that did start bleaching , split the day before or after I switched out the light . I can’t remember but this is what they look like now

You should be feeding every day

Definitely feed more. Besides being an important part of the carbonate cycle in reef ecosystems, fish poop supplies important nutrients to phototrophs or mixotrophs like corals. FWIW my systems get fed multiple times a day with spectrum pellets.
