Regarding the small daily water changes...
From Michael S. Paletta's "The New Marine Aquarium"
"After experimenting with just about every water-change scenario, I now
employ the routine of a 5% change every other week. I've seen visible improvements in my tanks with this water-change plan. (Other equally successful aquarists have different schedules: weekly changes of 5%, biweekly of 10% or even a very small daily water change--in the order of 1/2% to 1% of the tank's volume.
Old-school hobbyists often practiced large water changes of 25 to 30%, but these tend to be more stressful on the livestock and are not recommended for typical marine aquariums except in emergencies or major rescue efforts.)"
Different strokes for different folks.
