Couple questions that need to be answered before people can give suggestions.
Is your tank a 30g breeder with dimensions 36" x 18" x 12"? Don't see to many of these which is why I'm asking. Important to know the length and depth.
Are you going to be using injected CO2? If you want to go true high light you will need it or you grow algae mainly.
Are you open to LED lighting? or do you want to stay with florescent?
