ok so after hearing so many good things about Purigen I though I would give it a go I got anuf to treat about 500g for a 135g I placed it in a ac110 on top with only a sponge as the other media in the ac110 it's been about a week or so my nitrate level was 10 and now it's 15 so the only change was a bad one and this stuff is already turning brown ish in collor
is it because it is sitting right on the sponge
