Not sure salifert kits are reliable for phos and certainly don't give the low readings.
Results of poll surprise me, I don't believe that many people are really sub 0.03 - not using the dd merc kit

Inlinkman - I use nopox and caulerpa export to control nutrients. The brand of carbon is a cheap one we got on a multibuy (not fair to name but it was acid washed)
