A healthy growing Paletta pink tip should have plenty of tips that have the pink reach down a good 1-1.5".
At 300 or above you should be able to achieve that. If you can't get that at that level your spectrum is incorrect or you don't have a original Paletta pink tip. There are plenty of fakes that only show pink in the very tips.

Used to frag a 2 inch circumference every couple months to keep it from shading corals below it. Colony and all its frags all STNd followong anminro chiller mishapnwhere it was the only coral affected.
