Can any one explain mechanical,chemical and biological filteration in detail?

  • We are currently upgrading MFK. thanks! -neo
I meaning biological filteration that is nitrogen cycle ? What does it actually do? Does it reduces nitrates or increases nitrates?

Now I can understand lit bit . Nitrates cannot be converted into dissolved nitrogen right? Nitrates after long term exposure is harmful right?

Both correct. Waterchanges are the best way to get them out

Hello; There is some value to having live plants as they can take up nitrates. The benefit is a bit limited according to some. It seems a lot of plant material will need to be harvested in order to make a big difference. Still worth having.

Water changes (WC ) being the more practical and reliable way to reduce nitrates. I am more inclined toward smaller and more frequent WC schedule myself.
 
Regardless of planting or srocking I do 50-70% a week on all my tanks and nitrate stays undee 20
