I am just getting into looking to do my own DIY LED project. I know where to get most everything I need. My question (for the time being), how many LEDs do I need? I currently have a 6x39w T-5 Current fixture over my 40g Breeder. My tank primarlly houses SPS with an LPS garden on the bottom (no sand!). Also, is there any way around a Buckpuck driver, is there plans to make my own?
