Hi guys,

Can anyone suggest me 2 x T5 39W bulb combination that will give me the Radium (20K) color? What do you guys think about the following combo?

1. UVL Super Actinic + Fiji Purple
2. ATI Blue Plus + Fiji Purple
3. UVL Super Actinic + ATI Blue Plus

Thank you guys.

The reason I am doing this is because I can enjoy my tank even after my 2 x 250W MH are off.

I would say two ATI Blue plus would be close to that. Or that super actinic and the blue plus you have up there. That would be close to a 22000k look

It would be hard to get an exact 20K look with only two lamps.

I think you'll come closer with the ATI Blue+ and a 14K color bulb like the KZ 14K or the ATI Aquablue Special
