This topic normally falls under marine tanks, but does anyone have
experience with Aqualine Busche 5K 70w DE bulbs? The unit ordered comes with
10K(13k) or 5K bulb options.

The kelvin temperature 5k, I have read, could promote some algaes versus
kelvins 6500. It may not in this format as actual temperature may be
higher.

Please help
