Will this be enough?

According to Sanjay a 150W 10K XDE bulb run on an M81 HQI ballast will produce a PPFD rating of 61. Will this be adequate for MOST sps corals in a 29 gallon as long as all other aspects of husbandry are good?

Sounds good to me. Add some actinics and I'm sure you'll be happy.

I was thinking about it, but why spend the extra money if all I have to do is replace the bulb?
