The Cycle

[unknowntbeast]

Nitrate is the end result? The usual answer would be yes. But riddle me this...In lakes and ponds and whatnots, I assume the nitrogen cycle occurs there too. So after everything is nitrate, what happens? If nitrate levels get too high, then fish die. But since the fish in these waters are not dead, something must have happened to that nitrate. Is there another part of the cycle? Is it evaporated along with water? If nothing, then why are these fish not dead?

Just wanted to know.

This is where yet another difference between large natural water bodies and small aquariums comes into play. I was shocked to find out, some time ago, that there are several ways to design nitrate filters, so I investigated it (there are several interesting threads on it here at TFF.) Turns out that its definately not worth the effort, as changing water is easier and more effective but it showed me that yes, in nature, the processes keep on moving beyond the short segment we study and yak about so much here in the hobby.

anaerobic bacteria convert nitrate into nitrogen, which gasses off.

Also, In Nature,,,there are rains,currents,and tides to carry excess organics away. Not so in glass box of water.

Forget about just carrying away the nitrates. Plants remove nitrates quite nicely. My heavily planted tanks require that I add nitrates in order for my plants to have enough nitrogen to grow.
