You can see the card here and what is says.

OK, use the bottom line of numbers.

OK. As far as the bottom line of numbers, what do I want to be under? Where do I need to be?

Under .03 ppm should be fine:

I don't know how you can tell the difference between that bottom set of numbers. Elos is way better than that.

You should strive for 0. Even at 0 people can have algae problems. You have to make phosphate hard to get.

There is a difference in person, but ya, low end is close.
