What can I expect to see as far as growth with a single ended 250
20k watt radium bulb over my acros and montis?

Anyone with 20k radiums, how do your corals grow under them?

this is not from experience... but from lots of reading.
certain photosystems will grow real fast under blue light (generally green corals... and a few others). it just all depends on the coral itself
