I have a 55G Cichlid tank that has two 24" stock hoods. The lighting has a really dull yellowish hint. I really like the look of the light on reef tanks and on frontasa tanks. Since there is only one tube per hood I assume I can't use an Actinic bulb (too blue right). What is the best option? I don't like the look of really white light either. I want something that looks literally "cooler."
