I hope this isn't too off topic for the post, but the mention of different shades and current densities promted me to comment.
I am getting some pictures sized and will upload them to the album page soon. I have been getting a nice dark blue and black with 4.5 amps per square foot. The red from my setup is not bad at 4.5 amps, but could be better, although it may be the ph which I am also working on. I am about to start testing more at higher amps too, as I need to cut the cycle time down.
