Aquarium Advice Addict
I am going to purchase a new 96w actinic bulb for my 36" coralife lunar aqualight and there are 2 choices 460nm actinic 420nm actinic and a dual actinic which has 460/420nm There there is dual bulbs that have 10k/ daylight I am a little confused on why 2 different types of actinic bulbs and also daylight verses 10k could someone shed some light on the topic. no pun intended lol
