growing zoas

[chris88]

I have had about the same growth rate when i ran a carbon source (vinegar)to get nutrients really low and when i let me tank get a little bit dirty. I dont know what i could be doing differently. i also notice no difference in tap or ro water. The only thing i can think of is that i do not do water changes. i dont know if that is whats causing them to grow but its something to think about.
