How of do you change bulds? MH & T5
I've always been under the impression that my halides needed to be changed every 6 months. I run 2 x 250W 20K XM's single ended. I just saw someone changing them every 12-18 months. Am I changing these way to oftern?
I also just bought some T-5's for supplemental actinic light....how often should T-5s be changed? |

the actinics can be changed whenever you think your tank isn't getting the appropriate "blue". Corals really do not "need" that much of it and most bulbs offer in excess of that type of light. So the answer is...(imho) at least 12 month to 18 months - and beyond if you want.
