Adding 40W flourescent 20K or actinic?

[newsalth2o]

Have 80 watts of t5 HO with a 10k and a 420 actinic now adding some more light. added first sps and I know it needs more light. So which is better just to increase strength for coral growth.

Lose the actinic and use ati blue plus for one and a purple plus for the other the color is nice and par is awesome!!!
