Mixing Zeo and Brightwell
 

I'm using Brightwell Koral Color and Zeo Coral Vitalizer at the moment. I used Zeo a year ago and decided to give it another try for a bit. So I picked up Coral Snow and Pohls Extra. Would it be ok to keep using the Koral Color with the snow and pohls or should I stop using it?

I'm sure that is fine. I ran that combination for a while before I decided that the Koral Color didn't really do anything. That was based on no visible changes within 4 months or so.
