I made a switch from carbon filtraion with a whisper filter to sticking a fluval sponge in it for only biofiltration. I have read both sides of the argument...carbon takes out minerals that could be helpful, but also filters out harmful chems. I have live plants in my 15 g so I figured it might be better for them and fish to just have bio. My 5 only has frogs. The switch was a itte annoying building up the bio filter by stuffing both into the filter, limiting water flow, to build up the bacteria on the sponge.
I am thinking that my city tap in a building built in the 1920's is probably not the healthiest for fish and maybe perhaps I should have kept the carbon in. I think there is a high iron, and high something that turns stuff pink. On top of chlorine in the water (and chloramines). I condition water of course, but I wonder if carbon woud get extra chlorine. I read that it filters out ammonia (I thought that was the bacteria alone).
What are your opinions on this?
I wanted something that was the most natural, since carbon doesn't filter the ocean, I figured strictly bio filtration would be ok. But i get caught in crazy ideas too, so I don't know if I am nuts, NVTS, nuts.
thanks!
