The Grim Reefer
Ready for some NOBALL!!!
I have 4- 48" retro fit over-driven with a 660 ballast from reef geek. I'm getting to the 6 month time frame and going to start to change out the bulbs in a mixed reef with some sps frags at the top of the tank.
I have 3b+ and one atinic white now and am switching to 3b+ and one p+.
Question : should I change one per week for 4 weeks...can i replace them all at one time....or what ??
One at a shot every few days or so is how I'd do it.
