The brand, im not sure. It was a unit purchased off Ebay. A 5stage aquarium setup.
Ive never heard that the colder the water is, the longer it takes. But that seems right, b/c the water here is colder than all $#%&*#$!!!!

Ok, it seems that im gonna go ahead and filter out a few buckets of RO/DI water so I dont have to wait around for it when I really need it.

Thanks all.
