Do you find that is better than having it run for an hour or a few hours constantly? I am using ghl also changing about 1gpd in a 110g total volume system
Probably no real difference either way, but I figure it's more like a constant water change this way, kinda like the ocean. And it's less wear and tear on the doser. The rollers are plastic and they got hot during continuous runs. When they get hot they are more apt to wear down. At least that has been my experience in the past with other dosers.
