Radium On a S51 Ballast(HPS)

[stephane]

Yes the tips is becoming smokey a bit but they still look awsome and bright still to brigh for some LPS like the candy can who realy have a hard time in the bottom of the tank

IMO they are even beter than when they are new or is the coral color who make the difference I dont know but the color of acro are awsome and the grow is very fast ! (but it suck calcium like mad)
