I moved my hanging basket hybrid Neps inside for the winter and have them in a 55 gallon tank with four 40watt flourescent bulbs on top. One bulb is a Coralife 10,000 K and the other 3 are the bulbs that come in an Oceanic Triple Bulb Aquarium Strip Light. I am planning on changing them to 10,000 K's soon. The 3 bulbs are probably close in type to the old Gro-Lux bulbs. Anyway, they are turning the leaves of my cocciena (badly mispelled!) deep burgundy. Is that ok? Do I need to use the 10,000K bulbs or are these ok then? Thanks.
