Dry Ferts to go with Flourish Comprehensive
Hello I have two small low tech tanks (one gets excel) and I have a large bottle of Flourish Comprehensive that I would like to use up. Is it okay to use dry ferts for the npk along with the it?
Also I have looked around a bit and it seems most are sold as a set including micros. Is there anywhere that's sells only the macros?
I'm definitely a beginner and not sure about building my own mix just yet.
