This is not efficient. You export more nutrients by doing bigger waterchanges less often, obviously the most efficient would be doing 100% waterchanges, but that would be a bit shocking for the system! I have found over the years that doing 20% bi-weekly is more beneficial than 10% weekly. You use the same amount of water and salt, but get more benefit IMO. This is why I don't care for the high alkalinity of IO.
