So i have been wondering , my zoas are very healthy . But since i swopped lights the tips of tenticals lost their color , young ones have their color but loose it soon after . The previous light was almost the same but the new one only had one uv led extra . Could the uv be the cause ? The first light was a 1w uv and now it has 2x 3w at 70% . In the pic you can see the young ones have full color
