Hi,

Anyone running 20K mh without actinic (vho) supplemental?

How does it look?

If you visit Saltwater Paradise in Irving, all his tanks are lit that way.

Honestly I think they look too blue. But I also think that in the long run, you pay for the same amount of watts but don't the par level to the corals for the money. Do a search on the par levels of 20k bulbs on your type of ballast versus a 10k bulb.

Marc and Rick,

Thanks for you input. I'll have to get over to Irving to take a look.

Are the 14k bulbs about the same?
