Help maxi mini bleaching

[1979fishgeek]

hi guys

I have owned this maxi mini for a year, it's been in the same position and my tank parameters are very stable, temp has not changed neither has lighting, the only newish change is this time of year the sun is low enough to hit the tank in the afternoon, all my sps, lps and softies seem to enjoy the additional light boost and it's not the first time the Maxi mini has had natural sunlight. But in the past few weeks it's slowly bleaching. It's still eating when I target feed and is really sticky. It's not trying to move either...what's going on how can I stop it?

One of mine recently bleached as well but I was surprised to see it completely recover in a couple weeks. I believe my bleaching event was related to lighting.

I am assuming it the extra sunlight on the tank, I just can't think what else would cause it? I don't even run my tanks temp high, prefer 24C highest it gets is 26C in the summer. Just so strange it's suddenly bleaching?
