I have the coralife 4x65w pc's and i was wandering how can you tell when its time to replace your lights. I have had mine up and running for about 8 months.
Some folks say 1 year +. I started replacing my 6 - 65watt PCs at 8 months and did 1 every 2 weeks. The plan is to now get on a 9 month rotation. I have yet to decide on the MH bulbs what I'm gonna do but they are only 1 month old.:yes:
