dpotts Posted July 9, 2009 Share Posted July 9, 2009 Well my 29BC has been up and running for about 1 year now so I guess it's time to buy new lights. Do I change both at once or do it staggered over a couple of week? Also, should I shorten the light cycle for the first few days until the corals get used to the new lights? I have softies, LPS, and zoas...plus 2 clowns, a 6 line, a yellow watchman and the standard CUC! Thanks. Quote Link to comment Share on other sites More sharing options...
Zarathustra2 Posted July 9, 2009 Share Posted July 9, 2009 I've heard of a few methods. 1. Stagger lights at 6 month rotation 2. Lower your photo period to 6 or 8 hours then increase by 2 hours every few days/week. 3. Add a layer of screen door mesh over your tank then remove after a week or so (the one I use) Quote Link to comment Share on other sites More sharing options...
JamesL Posted July 9, 2009 Share Posted July 9, 2009 Pretty much Zarathustra2 has all of the tips. I recently changed the bulbs in my MH, and I cut my lighting schedule in half. I am upping it by an hour each week. So far most everything seems happy with it. Though I have two Acan's I am watching, as they are not happy ... yet two others are just fine.
