I stopped doing the whole “start on the sandbed, move to the lower rocks move a little higher, then to the final spot” game. Or the “put on a frag rack and slide it up the glass over weeks” (which is actually counter productive. Most tanks register higher par at the glass down low than up high). I lost countless frags having them shuffle all over the tank every couple weeks. Every single acro I get goes straight to its final spot the minute it hits the tank (excluding dipping and all that, I just mean once it is fit for the display). I don’t stage them or light acclimate anymore. Yes. Some of them bleach quickly. But I haven’t lost a single acro in the last year or so since I started putting them directly where I want them. Hope that is of some help
