oh i forgot to mention no water changes until a nitrate spike and rite before adding fish..i agree with Hallyx and for some reason in the back of my mind i wanted to say dont let the ammonia go above 4ppm but i read elsewhere to keep between 4-6 yet i still think letting it go above 4ppm will cause some issues, either killing off bacteria or something.i dont remember what it was....good call Hallyx i forgot Prime locks in ammonia..i usually use stress coat and used my prime on occasion.i just got my two 10 gallons from storage to re set up betta tanks and will cycle them..so im glad you jumped in and added a few things :)

Depending on the bacteria, ammonia over 5.0ppm can stall the cycle (although I've cycled quickly at >7.0ppm). Same for nitrite.

Many keepers feel livestock that produce >4.0ppm/day ammonia is overstocking. So an ammonia-handling capacity >4.0ppm/day is redundant. Bacteria grow to oxidize just the amount of ammonia produced by the livestock. No more; no less.

Stresscoat does nothing to detoxify ammonia. Prime, AmmoLock, Amquel+ are the big three for ammonia. Although there are others.

that makes a lot more sense than what i was thinking.i knew there was logic behind it but couldnt remember exactly :) i also havent cycled in over a year so im a little rusty...and i knew there was something i wanted to buy today when i got off work.. Prime..i got enough for one more water change.i need a job at a pet store.then i wont forget ;)

help please. Suddenly tank out of cycle and won't cycle

Hi, (sorry this was supposed to be a separate post, not sure how it got posted here)

I have had my 10 gallon tank for 1.5 years.

I have 2 small guppies and 2 danios (all of which seem to be doing fine so far, fortunately)

For 1.5 years the tank has been cycled fine.

Suddenly I see the ammonia go up to 0.5 and then 1.
I checked the pH and it was 6 (probably less, but that is the lowest marker). I am guessing that the low pH killed the bacteria.

I brought the pH up to 6.8-7, and now the ammonia level is up to 8.

I have done 50% water changes every 2-3 days for the past 3-4 weeks and the ammonia level is only down to 4.

I have added 2 bottles of safe-start over these weeks but it does not seem to be helping.
I always use water that is treated to lock out the chlorine when doing the water changes.

My settings:
pH 6.8
Ammonia 4 (8 if I don't do daily water changes)
Nitrite 0
Temp 76
1 air stone

I am a bit at a loss, it has been very long without any success.

I would appreciate any help.

Thank you!

Hi,

I am using the API master test kit.

I have also bought in a sample to the pet store to make sure that my reagents have not gone bad & they match up.

I also have a second newer bottle of the reagents to test the ammonia and I opened them up to confirm, and I get the same result.

I did find that for some reason there is now ammonia in the tap water (about 0.5), but regardless, if the tank was cycled the bacteria should eat that too, to bring the level down to zero.

Thanks,
Juggernaut

the next thing i was going to ask is for you to check your water straight from the tap.it might be best now to buy purified water from water vending machines..i would also call the water company and find out if this is a temporary thing with the water or what and let them know the situation.

but you are correct.if it is cycled that amount of ammonia from the water would go away fairly quickly and it wouldnt cause much of a spike like you have.i would stop adding any ammonia for a while and even avoid adding water unless its getting low.

?API master test kits are the way to go.i wouldnt use the strips as they arent always accurate but you seem to know that already.continue to monitor and let me know any changes.

Be careful with prime. It does lock up ammonia but with normal (api type) test kits you still test positive for ammonia. Because the test cannot tell the difference between locked and free ammonia. The danger is that prime also locks up oxygen so you add prime, test ammonia add more prime, etc, etc, etc. And the fish can actually suffocate.

Seachem has a multitest ammonia kit that tests for both type of ammonia. I would use that kit and only add prime for the free ammonia amount. I believe their in tank ammonia dots also only reacto to free ammonia.

my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

Almost 2 weeks later and still the same result.
Only difference is that now there seem to be algae growing on the plastic plants - not sure if that is a good or bad sign.

1 of my tiny guppies looks like he won't be surviving this....

I really am at a loss here...

really?im beginning to wonder if it has something to do with your tap.are you still using tap water?id hate to have you start again especially its been what nearly two months already.you really need some seeded material to see if that will help jump start the beneficial bacteria.even my 10 gallon i set up for my betta i put my fish in rite away and let the ammonia build up just enough and added rocks and artificial plants from my large tank thats been running for about a year and a half.

you can still save the guppy by putting them in a hospital tank like a 1 gallon tank with an air stone and clean the water every other day.keeping it in a low busy area where not any people walk and such if it is sick.but fresh water is the best cure for any fish.i would get purified water for it.

im baffled by your tank not cycling.can you uploading any pictures and or videos of the full setup so i can see how things are including the temp as well as the filter displacement and everything?

wish i was able to give you some of my media thats already got the BB on it..but if i was to mail it.it would be dead by the time it got to you especially hitting the cold weather.

also inform me of all the readings...nitrate, nitrite, ammonia, temp and such...lets see what exactly we have here.im now determined to get this tank cycled ;)
