I have now learned that I will need to have a fluorescent fixture that holds 2 bulbs for my 30 gallon saltwater tank. I plan to start with fish, LR
, snails, hermits, and some shrimp. Later I would like to try an anemone, feather dusters, and possibly (when my tank is mature) some corals.
I have heard that I should use 1 actinic bulb and 1 10,000k bulb in my fixture, but all the actinic bulbs I have looked at say they are meant to mimic twilight. So does this mean that I should have the 10,000k on during the day, then turn that off and have the actinic on for a little while before completely turning the lights out for the night? It's kind of confusing, because how can I have one bulb on & one off in the same light fixture? Help! I'm confused!
