Caulerpa ?

[psycho-killer]

hey, i bought a nice rock with lots of caulerpa on it, i placed it ontop of my ds about 2 weeks ago and have a pc light 18 watt about 10cm from it wich i run the same time as my halides. the leaves are starting to get yellow and some playces the leaves are white ? white new ones coming out ? yellow may my lights be burning them ?

hte longer bracnhes are on the top of the water level maybe move it down so the whole plant is underwater ? or put it somewhere in the main display tank ?

It does sound like you are buring the plant with your halides. either move it as low as possible in the tank or to the sump (if you have one)

im 99.9999999999999999% sure that the white tips and while leaves are new ones growing because it happens on mine all the time

ive never seen my caulerpa turn yellow though, so i cant help u there..
