    Is 20 watts enough for high light plants over a 25l tank?

    What kind of lighting is it? T8 or T5? Also what are the dimensions of the tank? I suspect it'll be more than enough. I used to run 2x18w T8s over my 24x8x8" tank, but that was probably overkill.

    Assuming good nutrients, then it's plenty.

    I'm running a 25 litre nano as we speak with an 18w PC T5, daily TPN+ and Easycarbo. No CO2 injection.

    One of the nicest, tightest carpets of glosso I've ever seen! No heater either.

    Humm in which case its either a standard incandescent bulb or a small halogen bulb, which in either case wont be very efficient so may not be enough. I guess try and see? :D
