It should be 2700k, upto 3000k will also work fine.
Don't use 6500k this is inaccurate.
Why not? Will you please explain why?

Higher Kelvin ratings don't promote the same type of algae growth, and are less efficient.
The standard answer to proper bulb is the 3000k and below.
Ok, so turf algae in particular likes the lower kelvin temp, whereas chaeto and caulerpa do fine under daylight spectrum bulbs.
+1 you want a type of algae to grow.
Can you guys link to your sourcing or researching on such a low K bulb? I spent some significant time researching and found most places & peoples expereince recommending between 5 & 6.5k bulbs.
so where the "standard answer" came from is perking my interest. Not saying anyone is right or wrong, just wondering the source.
An entire forum dedicated to scrubbers.
Sylvania pentron 13w 3000k this is a mogul base, GE 6 inch t5 is 4100k. Lowes has both bulbs. They also have 2700k bulbs and I just found my next project.
That is the website dedicated to scrubbers, I think anybody with one has been there. Can you link to the specific thread where the new trend is using such low K bulbs? While I havent been there in a while everything I have read before was the 5-6.5k bulbs. In fact it even looks like you have some pictured in yout write up lol? I'm not trying to argue, just would like to see some of the factoids past some saying 'told you so'.
Work with people a little. For a brand new member to jsut show up and go 'this is wrong' is gonna make people scratch thier heads a little. Especially more so when people have tried different bulbs, distances, combo etc for some time, even over on ATS its the same way. I will say up front post count has nothing to do with expereience, and thats why was asking your sources.
Well,actually,I've just changed my light into led.
