I will be using 400se bulbs on a coralvue ballast and vho's actinics bulbs on a 660 ballast. Which Reeflux bulb will be best with this application, the 10k or 12k
I have two 10k not even broken in less than 100 hrs. for sale for $40 ea. I didn`t like the color so I went with the 12K. If you are unsure I can show you my tank w/coralvue ballast w/t5`s and 12k`s LMK Tim....
