Title: gave my fish finrot
Review: i had smaller tanks with a small bioload. it gave my fish finrot. in the other tank i didnt have it in there as long and the finrot isnt as bad.didnt have issues before adding purigen.i tested my water and it was fine. it seems that whatever it did to my water, there wasnt a test for it.my once beautiful fish are now raggy ;[maybe just get this stuff if you have a big bioload and a messy tank.i just wanted a filter media that i wouldnt have to keep repurchasing.this is an expensive purchase for me since i've bought the purigen and several extra bags for it.
Is the review positive or negative?
