updated pic, taken today on the 14 - May - 2013
under purple blue white and near UV leds,
white at 50%
blues 100%
purple & uv 100%
(this is as much white LED as my tank gets)
So far this tank has been stable as hell, no issues ever, i did manage to break a heater while cleaning it thats about the only issue ive had in the past year and a half of it running.
Tank was weened off most zeovit products a couple of months ago now, swapped back to monthly water changes of 20L
If you set your tank up right you wont have issues!!
