[Polyp Addict]

Right now I have this set up, from front to back

ATI Blue +
ATI Purple +
ATI Blue +
ATI Blue +

I also have a Geisemann pure actinic and ATI Coral +. Whats the best 4 bulb combo that would look great, give me the pop and still grow my zoas and palys?

I like the combo you are currently running. I have 6 bulb and i run 5 blue plus and 1 purple plus. If i had a 4 lamp fixture i would run what you already are.
I changed out a blue plus in mine for a pure actinic and really couldnt tell any difference. Although it may make a difference in a 4 lamp fixture
