Need help lighting 24" 30 gallon tank

[SeahorseKeeper]

I plan on upgrading the lighting for my seahorse tank and need help picking out the light. It is for my seahorse tank and is mainly for macroalgae and easy corals like mushrooms, leathers and other seahorse friendly corals.

I have a 24" innovative marine dimmable dual LED that comes on the nuvo 38. Perfect dimensions for the tank. Might be more than you need but just throwin it out there. retails for 339 getting rid of it for 200 shipped brand new never used since im getting rid of the tank before i even set it up:squigglemouth:.
