Ditch the transformers, all you need are a couple of *7805 voltage regulators (5V) for powering the single colored leds, and a *7812 voltage reg (12V) for powering the arduino and a cooling fan. Here's a link to the ones I use all the time- they're rated for 1.5 amps ( more power than you'd ever need)


5 Volt -

225 Gal, Glass "Reef Ready" w/ twin Iwaki Pumps & 2 Ocean Clear inline filters.Lighting- Custom built DIY 600 watt LED system, BlueFish "mini" Led Controller,iAqua Aquarium Controller , and a 20lb CO2 system w/ Milwaukee Ph Controller.
