Ed&Sandy,
You may be the largest system that I have been following so far. To be honest, I have not been looking for this aspect of AlgaeFix dosing until now.
FWIW, it would not surprise me if it were established that there is a maximum amount of AlgaeFix that should added to a larger system at one time.

Jrw,
I will following your results with your size system as well. Please keep us posted.
