Switching from AP700 to XR30

[REEF_TO_KEEP]

Hello,

I have two AP700's in my 150 gallon mixed tank. One of them has a fan failure. I am planning to replace them with two XR30's.

Any advice to during and after switching the lights to ensure the corals are safe and unstressed?

Thanks

If you haven't purchased the xr30's I would look at other fixtures. You can do a combo of Reefi's and Quanta Helix bars or just the Helix bars alone.
