Out of curiosity, do corals generally tend to grow slower when under heavy "display" actinics? I know there are so many other variables, but in a general sense, assuming other variables are equal, corals are under those very heavy actinic lighting(towards the 20,000k levels)do they grow slower than when under much more balanced white daylighting(closer to 10,000k)?
Hi, I have this 2.5/ 3gal fluval that has a freshwater light, I may have already posted this question somewhere else. BUT I am thinking of purchasing a Par 30 or 38 bulb on a gooseneck, with the hopes of doing softies-- generally a zoa garden with a goby- main goal but MAYBE some LPS/ SPS? depending how it goes down the road- i do not need overkill lights at the current moment. But these lights only have an on off, there is no switch to only put on the actinic. I was wondering should I get an all Actinic bulb as well, or should is there something that can provide some "moon light" at night. or is that just unnecessary all together? Here is the Bulb i was planning on, if anyone knows of a better one please let me know :-D I am trying to do this tank on a shoestring as much as possible because it is so small, i just do not want to spend hundreds of dollars on a light. https://www.amazon.com/gp/product/B00CXTZN2Q/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=A2TWRNEH2276JE https://www.amazon.com/LUMENTEK-Aquarium-Light-Lighting-Aquariums/dp/B01G4BRRN6/ref=sr_1_1?s=pet-supplies&ie=UTF8&qid=1469562829&sr=1-1&keywords=par+38+reef+bulb Any opinions and recommendations appreciated.
