I mean way cooler. It looks like my chiller is only going to run in the summer now.
3 years of running 400W halides... 3 years of wondering why anyone would use halides instead of T5s.
I hope my corals like the 250s as much as I do
Now with 400s I had to be
real careful breaking in new bulbs, or I'd cook my corals (acros too). I'd start off with 6 hours for the first week, and slowly work up. Raising the lights isn't an option.
How much does everyone cut back (if at all) their 250W halides with new bulbs?
