Thanks for all the advice. I know 10 ppm
is not bad, but I would still like to try and get it to 0.
I will try and rinse out my filter media more often, I would only do that once in awhile. I also change the sponge media in the filter about once every 2/3 weeks, maybe I should change it more often?
As for the water I am using, I am using filtered tap water, I have an everpure purifier: Everpure H-300 Residential Water Filter Cartridges : Everpure Residential Replacement Cartridges : Everpure Filter Systems & Faucets | efilters.net
I also add seachem prime: Seachem. Prime
Do you think that combination is good enough?
