Does ammonium kill bacteria

[CHOMPERS]

Only in the thousands of ppm.

Ammonium and ammonia are basically the same, chemically.

When you don't know what you are talking about, sometimes it is better to not say anything.

I thought i read once that to much ammonia can kill bacteria or atleast keep them from producing

Yep.

The toxicity of ammonia is pH dependent.

Is anyone going to look this up?

It says so right here: http://www.teamaquafix.com/ammoniainwastewater.aspx

I figured since these people work with ammonia and ammonium day in and day out, they'd know what they were talking about.

And I'd also expect ammonium's electron configuration to be the same as ammonia's, therefore, except for the positive net charge, it should act the same was as ammonia. After all, Nitrosomonas take both up.

Yep.

Exactly what I was hoping you were going to explain, suppose I'll have to spend half my work day on Google (just as well I'm the IT guy or I'd probably get into trouble for not working!)
My interest is because I have low Ph problems with my tanks and wanted to know if that was making the Ammonia more toxic when doing a fishy cycle,

Yep.

AOB (Ammonia-Oxidizing Bacteria) only utilize ammonia not the ammonium ion. The levels of ammonia to ammonium vary depending on temperature and, more importantly, on pH. At lower pH values, most of the ammonia is in the ammonium form leaving you with a lot of nitrogen that the AOB cannot get rid of and conditions that would inactivate the ammonia-oxidizing enzyme. The ideal pH for ammonia oxidation is between pH 7-8.

According to the link Juxtaroberto provided.

God damn it. I was thinking of plants. Oops.

I also can't seem to find a "I just put my foot in my mouth" smiley.

Hey i have ammonium of 4-5 ppm ive been dosing prime daily.


My question is will to much of NH4 (safe ammonia (ammonium)) kill of good bacteria?

Question would be, which bacteria.
Certainly not the ammonia to nitrite.
But, high levels of ammonia can slow/stall the development of the nitrite to nitrate.
2-3ppm ammonia levels have been the target for sucessful cycling.
At higher levels most have issues waiting for the nitrite spike to end.

you're doing it wrong

I think you mean ammonium and ammonia
are basically the same tautologically

if people did this the internet would be down to about 3 pages. LOL

granted theyd all be citing fictious sites.
