filter floss and Iron
Has anyone noticed polyester filter floss absorbing/adsorbing iron. I
change the media in my eheim yesterday and I noticed all the floss
was a rusty brown. Also before changing it I tested the iron (new
test kit syndrome :) ) and the Iron was about 0.3ppm later I tested
it again (NTKS) and it was immeasurable. Now it could either be the
floss, which was the only thing I changed in the filter or the plants
sucked it up. What are your thoughts.
Thanks
