20k to 10k

What do you think?

I have just ordered 2 new Ushio 175 watt 10k's to replace my 20k Coralifes.

When I switch them out what should I reduce my lighting time to?

1. 1/4 time

2. 1/2 time

3. 3/4 time

4. same amount

I will and have been running Blueline E-ballasts. I also have 3 110 watt VHO's, two are Super Actinics and one is Actinic White.

My light hood is not adjustable for light height. All of my bulbs are about 3 inches above the water surface, under which I place glass tops so my bulbs don't get sprayed.

I have plenty of SPS and Softies. And my brand new Brain (Faviidae)!
