aqualight bulb replacement

[shyland83]

I have a 135 watt coralife lunar aqualight. Does anyone know how often the bulbs need to be replaced? I know they should be replaced before they burn out, but i cant find how long they last anywhere.

I see fish and shrimp in your tank description, but I don't see corals. If you're only keeping fish, you can let the bulbs go until they burn out. If you're keeping corals, the bulbs should be replaced before the color spectrum shifts too drastically. Some people say 6 months, some say 18 months.
I have limited experience with PC's, but IMO, 9 to 12 months max on your bulbs.

I am starting to add corals slowly but all soft and all pretty hardy. Some zoas, a mushroom, a kenya tree think, and some frag i cant remember what it is. I guess i'll change them out at 12 months. Thanks for the help.
