Cycle Question
Doing a water change percentage sufficient to reduce the
levels of ammonia and nitrite to levels that won't kill off the remaining
life, will still leave plenty of food for the bacteria. Keep...

Correction:
(B) should have read "and come back down via nitrosomonas" not nitrobacter.
Oops.
(B) Performing NO water change, will allow the NH3 concentration to go up

That's LD50, not ED50. Typo sorry!

Opinion on which sump to get????
George. I will put it easier terms for you so you understand. The aerobic
bacteria EAT the oxygen.
For aerobic bacteria oxygen is GOOD :)
For anaerobic bacteria oxygen is BAD :(

I will write this again for the umpteen time. This process is called
DENITRIFICATION. It is an enzymatic process that converts NO3- into H2O
and N2 (O2 is NOT produced).
And, once...

In order for the NO3 to give us N2 and H2O, wouldn't you need free H+
ions roaming around?
No. This process (denitrification) happens at an enzymatic/cellular
(anaerobic bacteria) level. The...

No, it doesn't. You are basically arguing that you start out with NO3 and
H2O
and it goes
No I am not arguing that.
2NO3 & 2H2O ---- 2NO2 & 2H2 ---- 2N01 & 2H2 ---- N2 & 2H2O.

I meant to write oxygen's that are removed from NO3- end up as H2O.
It actually goes NO3---NO2----N2 + H2O
