i currently have 2x175watt 10k MHs and im thinking about switching over to 20ks so my colors can pop a little more.
if i make the switch will there be any ill effect on my coral or fish with the sudden change in spectrum?
does anybody have pics or links to a tank lite with 20ks?

i also have 2x110watt vho actinics, just in case that would help my situation.
