Let me just clarify a couple of points.
The red led's from aquastyle are Epileds with a maximum current of 700ma (please note that the forward voltage is only 2.5v @ 700ma, a bit less than whites). So, you will not burn that out by driving them at 680ma BUT the red is a very overpowering colour and, to balance the colour, you would really want to drive them less than your other leds - that is why I suggested somewhere around 300ma. It is hard with small builds as you don't have large numbers of drivers to get the right drive currents across the different led colours but I would not have the red with you royal blue.
The red, along with others like violet and turquoise are not meant to be providing the core light requirements for your corals - it is pretty well established that blue/royal blue/neutral white provide this. These 'exotic' colours are to provide the extra 'pop' seen with some of the T5 tubes i.e. Fiji purple etc.
Also red does not provide much light - your Epiled only puts out around 70 lumens - so your tank will look dark. Some people are mixing a deep red, royal blue and turquoise - these 3 produce a 'white' light so your tank looks nice and bright but the 3 colours provide some 'pop' for your corals. This is what I will be trialling shortly.
