I finally got a light fixture for my tank. When I’m ready for coral (when coralline algae takes over) I plan on eventually using a custom schedule I created since the light has an acclimation mode.
I have not read much into zooxanthellae but I have a rough understanding of the light terminology used vía planted tanks so my apologies in advance if I confuse some terms. My understanding is that zooxanthellae are not as tolerant of par levels above 400 and the pur tends to be towards the lower end of the spectrum. I plan to keep an sps dominated mixed tank. I have just enough shadows for lower light demanding corals.
Since kessil locks in the required spectrum, I’m not worried about messing that up, but more so how much power is going to the diodes throughout the day. I decided to add more power to red (for morning) and green (more color + power overall) to mimic the look of sunrise into noon and appreciate the most natural looking color renditions kessil offers via Ap9x. The same for sunset. Please suggest how much I can drive up red and green leds without running into problems (I kept everything low to be safe). Still overall am I concerned on ramping up the intensity for both the kessil spectrum and red+green+violet channels will be too much over time? I understand violet (uv or near uv) should be ramped up with caution so corals can acclimate.
I drop the color and intensity to suggested and preferred (BRS) levels for aesthetic reasons around the time I look at my tank the most where the red look for sunset perfectly leads into the preferred settings (1500-1700).
So the entire photoperiod ends up being roughly 16 hrs. slowly ramping up and a fast ramp down. Would the settings for my photoperiod be tolerable or too stressful? Would ramping down too fast have any adverse effects due to ramping up slowly?
I have yet to map out par levels, so I’m basing it off of the settings provided by Randy from brs on an empty tank. I know glass reflections, rockscape and tank dimensions will influence par) but I will let the corals tell me via trial and error.
Please advise, I’m relatively new to reefing and looking to start collecting these animals and would like to give them the best chance.
Tank dimensions: 30”x15.75”x15.75”
The par readings for a tank with my dimensions would fall within the 4 centered rows and an additional column of points. The light is centered.
