I would just like to point out that you do have the option as well to Inject the Excel upon the infected areas direct.. This has proven to be even more effective if you have particular areas on leafs etc.. Turkey Baster, or the little measuring syringe that comes in the Flourish Bottles will work.. Balance is the Key though within the Ferts.. Micros/ Macros alternating each day.. Higher the light, the more in Check this must be = less algae along with good WCs.... Just my experience.... _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
