    A few weeks ago I bought a used biocube 29. The owner said the bulbs were 9 months old... Will I be ok with adding some corals or do they need to be replaced?

    I would replace them. Look at the ends of the bulbs and if they have brown/dark rings toward the ends then they definately need to be changed out.

    +4 (maybe 5?)

    IMOPE, PC bulbs lose their color spectrum in roughly 6 months, although the bulb would last much longer.

    Quote from Dr Foster/Smith:

    "The intensity of a bulb diminishes over time and even though the bulb will still light, it may not be emitting the necessary spectrum or intensity to support proper growth. In many instances, the diminished light output can encourage nuisance algae growth so it is important to replace compact fluorescent bulbs every 14 to 24 months. For reef aquariums, it may be necessary to replace the bulbs more often depending on the species being kept."

    According to this my 9 month bulbs should be ok. Agree or disagree?
