Hi, the 15W T8 tue over my 60L tank has gone in the last few days. I was originally running an Arcadia Original Tropical Lamp, but I wondered if there were any recommendations on particular tubes to go for, or where to buy? It's a fairly basic tank, with minimal live plants. I had been looking at Lampspec.co.uk, and there 5000k lamp, but I really have no idea whether 5000k is a 'good light' or not? Many thanks EDIT Actually, forget lampspec, once I add shipping, the shipping alone is more than I can get the Arcadia lamp for at my LFS!
