Thoughts on over skimming

What kit are you using to test phosphate anyway? Unless you're using a Merc kit or comparable, such a low reading is probably inaccurate.

Elos, the next reading above zero is 0.01 then it jumps to 0.1

Ya, likely not too accurate at that low number, but at least you know there is probably "a little bit". I find if you compare to a Merc kit both Elos and Salifert will show lower readings than the Merc.
