I have one of the older model Gyres (XF-150) from last year with the classic controller. I'm looking at adding a second pump to the other side of the tank, and was looking at the newer XF230/250 models. Does anyone know if they new controllers with those will operate the older pumps? I know the new controllers allow 2 pumps, just not sure if I'll need to replace the old pump as well. I'd rather not, as they're quite expensive and it works great, I just want to make sure I get two pumps that will work together.
