Coral Bleaching Recovery Time

[Fink]

Good Evening folks,

So about two months ago I got the hipargero 30w light for my fluval 13.5. I ran it for the first month on pretty much full blast. Around the 1 month mark when I was doing a mid-day water change (nice sunlight to illuminate the tank) I noticed that some of my zoas and leathers looked a little faded, and a few of the LPS had distinct patterns that followed the path of the hipargero light.

I took all of this to mean that I was bleaching the coral with too much light, so I did a bunch of searching on here and other forums and found the intensity that most other folks are using on this tank with that light.

Since then things have seemed good and the corals have regained some but not all of their original color. My question is how long does it take for them to fully recover?



TL/DR: How long does it take for LPS and soft coral to get their color back after they get bleached from excessive light.

Zoas do best with 95% blue actinic mixed with 5% white.

You can.blast as much blue as you want (as far as PAR) but hold waaaaay back on the white.

Fix your blue/white mix and you'll see improvements in 30-60 days

Thanks!

Not at home right now, but I'll try and get some later. To be clear, I've had some recovery, but they aren't back to what they were. The reds are still kind of pink, and the greens are skewing more towards yellow. I'm running 40% whites and 90% blues right now, and things seem to be getting better.

Is there any danger in going super low on the whites for a while? Like down near 20%. I was thinking if I go that low and the zoas start stretching then I can start ramping them back up.
