with cfls I know that you can get a large range of lumens and Kelvin ratings from what would seem to be the exact same bulb..I have also been having this problem with my chaeto though but I do not know the proper lumens and K
needed for chaeto so if someone would chime in with that information then we could solve this problem that we seem to all have lol
