I am trying to find the right led strip to make the diy chaeto reactor. I have seen the ones made with the 6500k white leds but I have also seen the ones made with the purple or reddish light. Which one is better in your opinions for growth?
this is what is commonly used when building a Chaeto reactor.
search around and you can usually find them a bit cheaper as well.
I have the 3:1 red/blue ratio. just haven't gotten around to installing it yet.
