Im running 2 ecoxotic Modules and 1 stunner strip on my 24g pod
I just got my stunner strip back today from being repaired so this is really the first time since ive had it that im using it
anyway my original thought was I would run my stunner non stop turn on 1 led module in the morning followed by the second one about an hour later and reverse that in the evening.
Although I have to say I was really surprised how much the stunner puts out and anyone thats seen these knows what I mean.
Will I have any negative affects on the tank or the stunner itself running it like this?
Per your post, I'm assuming that you are running 2 of the 'Panorama' modules and 1 'Stunner' strip. I am including links to PAR readings of these devices for your consideration, below.
Depending on the types of corals you are keeping, and their positions in your tank, you can make an informed decision on the lighting cycle for these devices, from studying those links and the PAR ratings within.
In general, most corals will 'photosaturate' at levels above around ~300 PAR. Some do this at lower PAR than that. What does this mean? Simply put, that they cannot use any more PAR than this for photosynthesis. More PAR will not harm them but is not useful either, until you exceed ~600 PAR. At this point you reach 'Photoinhibition'. This means that more light inhibits growth (ie- it actually harms the coral). Why this happens has been attribute to the generation of free radicle compounds within the corals' symbiotic algae (which are called zooxanthellae). Peroxides in particular, are destructive compounds generated in abundance from photosynthesis. Under PAR levels below ~600, these algae produce enough protective compunds, known as peroxidase which destroy peroxides.
Above the ~600 PAR level, the algae cannot produce enough peroxidase to keep up, and suffers. The result often being bleaching of the coral. So
avoiding these higher PAR levels, is the rule. Some corals may be acclimated to the higher PAR, SPS in particular, if done so gradually.
A lot of information, which you may already have, but is here for your consideration in any case. By studying the PAR readings in the links below, you may notice that the Panorama's emit more light, but the Stunner's have a narrower distribution angle or 'spread pattern'. Consider this in your evaluation. Hope this helped.
