good advice

Plants love old fish water. My garden stays green well into november because of it! Rinse your filter media as little as possible to restore full flow from your filter. Think of the gunk in your filterpads as life support for your tank. I've learned a lot by participating in this thread, thanks forest. I'm still trying to wrap my mind around this nitrite spike thing. I've seen a couple of t
Other threads about persistent high nitrite and each seems to be different. My theory is that stage2 bacteria that process nitrite get killed or harmed, then nitrites build up and nitrate is no longer produced. What harms the bacteria colony is my main interest at this point in time. Could be chloromine accumulation caused by too infrequent or too small waterchanges, or lack of dissolved oxygen, maybe somthing else. If anyone has ideas please post. In established, well cared for tanks, nitrite should never spike.
Please remind me forest, what size is your tank and did you do regular waterchanges before you had your problem? Seachem Prime detoxifies nitrite as well as nuetralizing chlorine, chloromine, metals. Its a little expensive for the size bottle you get, but its super concentrated so it will lasta long time.
Thanks to all who posted on this thread and forest, thanks again for playing!

FWIW chlorimine does not accumulate in tanks. Not even is water systems. It breaks down to ammonia and chlorine gas. Water systems that switched from chlorine to chlorimines discovered they had to flush out the systems due to algae build up from the aerobic bacteria. The effect is so great that most if not all the chloramine is broken down in the water system before it ever gets to your faucet.

I have noticed the nitrIte spikes which are much worse (pegging the test kit) in unplanted tanks. What I have found out is that by stopping feeding the nitrItes drop down quickly. After they drop down then normal feeding does not result in nitrIte spikes. So what I do is add a fish and not feed that fish the first week. In my planted tanks I still see a 1 day nitrIte spike. but even that spike is only 1ppm or so.

so bob...

I really want to understand this. Overfeeding produces large amounts of ammonia Plants take ammonia that would have been converted to nitrite by bacteria? That would explain why nitrite spikes in planted tanks are less severe than in unplanted. Is there anything you could add or please correct me if I have it wrong. Again, thanks for your knowledge and experience.

yep :) the reason you get nitrites will be due to excess ammonia. Generally speaking, in the majority of cases, two types of bacteria help complete the nitrogen cycle- Nitrosomonas and nitrobacter.
The former oxidises ammonia and turns that into nitrites while the latter converts nitrites into nitrates.

when the nitrosomonas colony process an unusually large amount of ammonia into nitrites, and for some reason the nitrobacter colony is not large enough to process the sudden excess of nitrItes into nitrAtes, your tank will experience a nitrite spike.

Plants can definitely help by consuming the ammonia :)

thanks

Does nitrobacter colony rely exclusivly on bacteria produced nitrite for sustainence?That would explain why it cannot be as large or larger than nitrosonoma colony

You have it basically right. Only the ammonia does not have to come from just overfeeding for instance.


But the plants sucking out the ammonia preventing spikes is correct.


Meanwhile there still is aerobic bacteria. Especially in new planted tanks because the water is oxygenated by the plants and the plants themselves add bacteria to the system. That bacteria will expand and consume more and more of the ammonia. Just like in a plantless cycle.

But with plants you don't see that initial ammonia spike. You may see an inital nitrate spike as the plants prefer ammonia over nitrates. Then as the bacteri gets the ammonia, the plants revert back to nitrates and nitrates drop down.

So it's been a week since I've done a water change and everything has been going great!! Tests have all been consistent with
Ammonia 0
Nitrite 0
Nitrate (12/6) 20 , slowly climbed all week
pH 8.2

So happy to see things consistent !I'm glad I started this thread, learned a lot, got started on live plants, became proactive with testing, meet some of you, exposed to a range of ideas, started using prime, became a little better aquariest , sweated, giggled and cried.

I too have learned a lot since going online with fishkeeping. This thread not only helps you and everyone who posted, but also many people from all over who read it. Non members who type " nitrite spike" into there search engine might very well be directed to your thread. All who contributed to this thread have created a valuable and varied picece of information that is based on an actual, real world case, not just theory or science, but a real person with a troubled fishtank. Thanks to all!

Now that you have started the live plants you begin to see more changes, albeit slowly... eventualy once they establish, you will notice the nitrAte level begin to drop, while the amonia and nitrIte levels remain at 0..

Excellent values and glad you're happy.

Hopefully you will find out that you don't have to use prime in your top off water.

I have found over the years it is just amazing what our tanks can do when I mostly just leave them alone. With the exception of having thriving plants that is.


Congrates.

ps I like this forum also.
