Vho vs. PC

[whiti9]

20 gallon nano
Which do you think is better?
3- 24" URI's total wattage 225
3- 24" PC 195 watts
Not to sure which to switch to.

I didn't know they made 24" VHO's. I personally think the PC's are a better investment as you don't have to replace the bulbs as often, but they are more sensitive to moisture and vibration.

ehh not this argument again this could go on for days VHO vs PC lol

I have never had VHO before, but i really like my PC and i highly recomend them.:yes: :yes:

I would suggest getting an IceCap 660 Ballast and then you can switch back & forth or even mix & match.
A pair of 24" PC daylights & a 24" URI SuperActinic would be a good combination IMO.
Also - it is my opinion that on an IceCap ballast VHO last longer than PC bulbs, 12-14 months vs 10 - 12 months.
PCs have a small "Sweet Spot" that is significantly more intense than what VHO can achieve though. This sweet spot is a good place for more light demanding corals.

Can you use the icecap 660 with power compact. can you do that with every ballast?

Yes, You can use PC with the IceCap 660 as well as NO, HO (including T-5), and VHO.
Other ballasts can do this with the proper wiring. IceCap is the only one I know of that you can just hook up the bulbs and the ballast will figure out how best to light them.
