Hello
I've bought the overhead T5 lighting unit for my planted tank from this auction http://www.ebay.co.uk/itm/280766047570? ... 1439.l2648 and one of the tubes is in blue colour. I am wondering if this tube is doing the same job as the other 6500K tubes for plants or shall I better replace this tube with 6500K?
