Hi everyone,

I am looking a bit of advice, I have a discus tank and a marine tank, at the minute I am in the process of building a LED light for my marine tank, at the same time I have picked up a few bits and pieces to eventually build a LED light for the discus tank. For the marine tank I am going for white (mix of cool and neutral), blue (mix of blue and royal blue), red, green and UV LEDs. I am wondering what sort of colour mix would I need for a discus planted tank? I have ordered extra red and green LEDs, I know the green LEDs will do little for the plants but I am hoping that they should show off colours well. The reason I am looking into this now is that I am ordering drivers for the LEDs and they have a set delivery price of £10 so when I order the 7 I need for the marine tank it adds £1.50 to each driver but if I know I need 5 for the discus tank then I can order them also at the same time and work out adding less to each driver and saving me another £10 later in the year.

Thanks in advance for any help people can offer

Keith
