Im looking to add more colors of zoas and maybe another type of coral to my 7 month old 2.5 pico, I would like something with a vibrant red color, do any of you have recommendations for it?
I think you're looking for a phytoplankton blend that has high phycoerythrin content to make the fluorescent colors pop. I recommend the HBLF 'Cosmopolitan' phytoplankton blend. There will be an explosive change in color. I have two pictures of a bottle. I'll post them when I get home. Please remind me if I forget. The Cosmopolitan has restored intense reds and blues to once muted coral.
Red Goni for flowy, if you want something encrusting, Darth Maul Porites. Mine grows great and has a vivid red coloration. Not sure how strong your light is though, my Darth Maul is in about 230-240 par and pretty decent flow.
