TBH, I did exactly the same but eventually didn't like the way the stock lights suddenly just turned on, almost frightening the fish at times - hence going for the LEDs and the sunrise/set feature. I remember quite lengthy conversations with
@Pat24601 over the options. The colour is great but I do at times wish I'd gone for the JMB version, but that might just be the way in which I have them set up. My lighting schedule is probably on way too long so I'll be tweaking a lot of things shortly, including getting the dimmer set right so the colours are where they need to be.
I think the Bluefish controller gives more configuration options and if I'm right, I think
@StevesLEDs have replaced the dimmers, making it easier to dial in but they'll be better able to confirm that.
