So I have two t-5 bulbs that need to be replaced they are 5ft long. They supplement my chinese black boxes. I want my corals to pop more and get better coloration. I used to run the ATI blue plus or the aquablue special but I cannot remember lol. but I am not looking for a (daylight) bulb. SO I want something like actinic. SO here are some options I saw that could be good. ATI true actinic, Gieseman Actinic blue 420nm or the super actinic by Gieseman. Thoughts on these bulbs and which is the best bang for my buck for my criteria:makes corals pop,and get better coloration.
