i never knew that TOO much ammonia could actually kill the bacteria... so do you think that all the bacteria from my filter pads from my cycled tank are dead if i put em in the tank with 8ppm?

just incase anyones interested... i just read a long post on fishlore, and it sounds like beneficial bacteria cant actually "die", they just stop temporarily functioning at certain conditions. But it sounds like they will start re-functioning when they are placed back into their ideal conditions.
ok im going to do a water change and use seachem stability and see if i notice any difference. I cant believe that even with a whole filter pad from my eheim canister filter in the sump theres no nitrites.
read the sticky on cycling again. you get ammonia. your bacteria builds up. they eat the ammonia and turn it into nitrite. new bacteria forms and eats the nitrite, which creates nitrate. nitrate is removed via water changes and plants. you're at the starting stages of ammonia, you won't see any nitrite yet.

BB can totally die. pollutants in the water can kill them, as can media drying out. if they have no food source, of course they can die, just like any other living organism. they can also go into hibernation at lower temperatures and can die off at low enough temps.

"The answer is - they last basically forever. Bacteria are not human. They do not die from starvation (I am being somewhat general here) but bacteria have ways to survive when the conditions get bad which is why they have been around for so many millions and millions (billions) of years. The only way to kill a bacterium is to break its cell wall or poison it. Now this does not mean they have a lot activity but they aren't dead in the sense that the cell cannot turn back on and start doing what it does (oxidizing ammonia or nitrite).
I also read on this forum that there are land based nitrifiers that drown in water - this is simply not true. Nitrosomonas europaea (a common ammonia oxidizing bacteria - AOB) and even Nitrobacter winogradskyii (a common nitrite oxidizing bacteria NOB) are both found in soil (land) but when you want to grow them in the lab you grow them in water, plus they are found in aquatic environments. In fact, in the lab all strains and species of AOB and NOB are grown in water they are not grown on agar or media in a petri dish.
The major deciding factor of which AOB or NOB will develop in an environment is the amount of ammonia or nitrite, respectively, in the environment."

that's because no matter what, they will come into contact with water. from in the soil which will contain h2o, etc. so yeah, they will live in water, agreed.
but you can kill them off too. ever had a saltwater tank and let your live rocks dry out? you get massive die-off of bacteria which if added to the tank without cleaning said rock, can cause all of the dead organisms to spike your tank levels and kill off your fish. as they start to die off, they'll reek to high hell. so yes, they can die. the reason you can "get them back" is because new bacteria will seed and take over, not the bacteria that die off.
Just get it down to 4-5ppm and give it a bit of time. It will happen. By all means squeeze out your other sponges into a bucket of normal tank water and throw that water into the cycling tank, it's not gonna hurt your cause.
Ok so i got the ammonia down to 5ppm (definetly no more than 6 ppm), and added the first dose of seachem stability today. Hoping for the best.
i never knew that TOO much ammonia could actually kill the bacteria... so do you think that all the bacteria from my filter pads from my cycled tank are dead if i put em in the tank with 8ppm?
Why do you think they put ammonia in tap water??? It ensures our drinking water is organism free and safe!
You can kill bb a few different ways: cleaning w/ tap water, drying out, hot water, not enough oxygen exchange, and toxicity/contaminents.
8ppm ammonia is nuts, be patient! And hooking up the canister directly to ur new tank as stated above was a great idea!

I would hook up the canister but i have $300 of fish currently in that tank lol... Including my marbled motoro
