How to take good care of zoanthids?

[Felixc395]

Hi. I'm a zoanthid love just as much as the next reefer, but I'd like to know what I can do to make my zoanthids healthier and bring out their colors.

What additives to the tank are helpful for health and fast growth in zoanthids?
What are some ways I can make my zoanthids' color more vivid?

I'd appreciate as much advice as possible. Thanks!

I have found that my zoas have really taken off since my tank is stable with CO2 reactor...also Tunze's seemed to help.

What kind of CO2 reactor? How has it helped your ph? My ph always runs low.
