Still learning...
I am at a point that I need to star thinking about replacing my bulbs and am trying to understand the spectrum options and what they mean/do. I am running a 72" Hamilton fixture with 3 175w 10k MH, and 4 96w Actinic CF. I have a couple of questions;
1) I would like to go a little more 'blue' visually, but don't understand what the requirements of the coral are. Or does that matter, would any of the standard wavelengths be fine (10k, 15k, 20k)? Do I need to coordinate the MH and CF wavelengths to try and cover as much of the full spectrum as possible?
2) My initial thought was to go to like 14-15k MH bulbs and possibly the 420/460 combo bulbs for the CFs. This decision is totally based on what I 'think' it will look like so I'm not sure I understand if I should be considering other things, specifically impacts to the coral and/or tank health.
BTW, since I am still relatively new I have a smattering of all kinds of corals. Rics, 'shrooms, SPS, LPS, Polyps, Soft, BTA, etc.
