I have a twin tube fixture for my 70gallon tall tank. I'm not sure that I'm happy with the way the lighting looks. I have the 'standard' tubes that came with the fixture. They are All-Glass but really don't tell me anything else about the color/intensity. To me, they are kinda plain and the tank has just a bit of a bluish look to it.
I'm thinking that I may like a more 'natural' look (kinda a 'normal' light with no blue tint if that makes sense). My tank has driftwood, a rock cave, and many silk (read that - artificial) plants. I would say it's kinda a bit on the South American side. The fish are: Angels, Rasbora's, Rummies, Bleeding Hearts, Cory's, Clown Loaches, and my great looking Gold Nugget Pleco.
Any suggestions for replacement lighting? Also, could you please help me better understand what the different 'K
' ratings mean?
