Best Dog Odor Eliminator : Fluval Biomax Bio Rings – 500 grams ...
I have a fluval FX5 filter with the prefilter media and a bag of carbon on the top rack, 2nd shelf has 2 boxes of fluval bio media, and 3rd shelf has the filter floss with 2 boxes of biomedia. I’ve had my tank up and running for a month prior to buying the prefilter media, bio media, and filter floss. I have a 125g tank with a walleye and a couple dozen feeder fish (so a fairly messy bunch of fish). I’ve never had a tank with water so clear. Before I installed these, my water was fairly clear, just a little cloudy, but nothing that I would have worried about. However, after I put this in, my water was crystal clear.
