Phosphate never tested, I would get that tested with a reliable kit and go from there

Am I correct in reading that you've had the green acro for 4 months, it was green and then turned brown last week?

Or is a new acro?

If you've had it for 4 months, can you tell me:

1. Which salt brand you are using and how much weekly water change you are doing?

2. How are you dosing Ca/Alk/mg? Calcium reactor? Dosing 2/3 part? Which brand if dosing 2/3part?

3. Have you dosed anything new recently or added GAC/GFO recently?

My Bali Slimmer did the same thing.. It was merely a stress response after being moved about and stuck on a new rock, it's all nice and green again now.. It took about 1 - 2 weeks to revert back to it's original colour.

I understand from researching similar that the brown is an increase in Zoox to aid in the recovery after a stressful experience.

Think of it as chocolate for the Mrs when she's feeling stressed

Of course, there could be other factors, but if water params are ok, then just leave well alone and let it recover in it's own time. :beer:
