I'm using default ModSettings of VanillaGalore+SpaceAge Galore (Enable Ice recipes is false)
IceMelting allows productivity modules and WaterFreezing is also available.
Both have ratios of 20water<->1 Ice, and thus is infinite ICE with no inputs.
Maybe it's a bug that WaterFreezing is available with the default toggle. One mod may have overwrote the settings.
Should probably disable the WaterFreezing recipe with default settings.
or nerf it to require 80 water per ice such that it's resource neutral at the 300% productivity limit.
I figured the intent is to allow Nauvis and Gleba to export ICE, in which case recipe nerf has little impact and still allows productivity in water melting which is important for Fulgora.
