are you still feeding your cycle? i know you took the shrimp out a couple days ago. if you didnt continue to feed it you may have killed off your bactira.

I thought you could only kill off the bacteria if you didn't feed the tank after the cycle was already completed? I didn't feed my tank last time I cycled my tank...

you still have to feed it with fish food, ammonia, fish poo if you add fish. something. you removed the ammonia source and doesnt sound like you add anything to keep them feed. my guess is your not cycled now.

No way.. i thought your supposed to take the shrimp out once your ammonia reads zero, and let the cycle finish up, THEN feed the tank.. there was hardly anything left of the shrimp.

ill wait for an expert to chime in here but without some kind of food source i dont see how it stayed alive. with no ammonia type food source the ammonia type bactira dies. if they die then the nitrite type bactira will die shortly after.

add a pinch of food or some ammonia. that will tell you for sure. if you get a spike and it goes away in 24 hours your cycled..if it stays or takes a bit to show ammonia you are restarting your cycle

I thought that when you put in ammonia, or food, bioload, whatever, if it decays or whatever, and no ammonia presents itself, THEN you know your cycled.. When a tank is cycled, you not supposed to get any ammonia readings if you had livestock in there.. right?

correct you shouldnt get an ammonia reading. thats because you have the bactira eatting the ammonia. the bactira is a living creature. it needs a food source to live. during your cycle that is ammonia or the shrimp decompsing. when your tank has fish the food source is your fish waste and left over food.
this is the basics of it
food source = ammonia. ammonia type bactira eat it and expels nitrite waste. this type of bactira doubles roughly once every 12 hours.

food source nitrite. nitrite type bactira eats the nitrite and expels nitrate waste. this type of bactira doubles roughly once every 8 hours.

thats the reason nitrites show up after ammonia. takes awile for the ammonia type of bactira to produce enough food(nitrites) to substain the nitrite type bactira.

the way we do a cycle it produces a small amount of these bactira's which is why you have to add a small bioload to the tank and let the bactira catch up. technically you should be able to feed the tank enough you could do a full bioload instantly. but it would take a much longer cycle cause you have to feed it more, and more offen to keep enough food source to feed the bactira and wait for it to double enough.

but without some kind of food source to keep it alive they die.

You both are correct. The bacteria will not die off immediately in a day or so if not fed. zer0 is waiting for his Nitrates to show up. That is the sign that the cycle is done. then and only then does he need to feed the tank or add fish, cuc etc. He only has to feed the tank once a week to maintain the cycle.

Alright so the consensus is, i need to wait until my nitrates show up, then i can start feeding the tank once a week to keep the nitrifying bacteria alive? I'm not completely screwed, and i don't have to start a cycle again?

My readings go, 0ppm of Ammonia, .50ppm of Nitrites, and 0ppm of Nitrates.


Oh yah.. and small update.

I got my metal halide pendant, and the shimmering effect it has on the water is unlike anything i've ever seen before lol. it's so freakin awesome. Pictures when my mom gets home with the camera. I still need to hang it too..

this doesnt make alot of sense to me. he has nitrites right now. but he took out his ammonia source so he has nothing feeding the ammonia or nitrites anymore. if there is no food source how is it goign to convert? if you have no ammonia you have nothing to convert to nitrites anymore . which means you have nothing to convert to nitrates. with nothing feeding the cycle you have no cycle going on.
