Hi all, I am currently in the process of building a new ~1200L aquarium (240x60x70 dimensions) and am struggling to decide what kind of lighting to choose. The aquarium will be planted and populated with a group of ~12 discus and "maintenance crew" of ottos and other small hard workers. I've always had T5 lights, but am really interested in LED lighting options, particularly to allow also for dimming effects of morning/evening etc. - to make the aquarium as "natural" as possible. But there is a flood of options, all quite different as this seems to be rather new and evolving field of tech. For instance, I am looking at: GHL's Mitras LX line Kessil's A360 LED lights (would probably need few of these) Hydra FiftyTwo HD: Aquamedics ECOplant LED 90 Maxspect Razor 420r 320w TMC's GroBeam: Euroquatics E5 lamps: ...and many others. So difficult to choose. And in particular as my aquarium is indeed very large. Is there a clear advantage of LED over T5? I realise there are also some dimmable options for T5, but I have not seen any nice ready-made products; many are sort of DIY variants... Please can you help me choose a suitable lighting system for a 240cm long 1200L planted aquarium? Many thanks!
