Is my cycle almost over?


Ive been doing alot of research and its been confusing for me. I hope everything is going smooth.

its been a week and a half now my nitrites finally started showing up sky high, nirtrates also showing up 20ppm? im using the api test kits right now, and tetra kit.
My ammonia levels are a little low, but i bumped in back up to 3-5ppm


can anyone tell me what to do next? ive read that im suppose to being doing a 50% water change is that true? is so what do i do after that?

Since you have nitrates showing up already, all you need to do is wait for the nitrites to hit 0. Once the nitrites hit 0 you can stop dosing ammonia and keep checking it until you get 0 ammonia and 0 nitrite. Then do a water change to get your nitrates to a reasonable level (less than 20-40pp or so), then it's time to add fish.

If you don't add fish right away, you'll have to keep dosing ammonia or your bacteria colony will starve.

This. Make sure you feed ammonia until you have your stock do it for you.

Just keep dosing ammonia until both ammonia and nitrite hit 0 within 24 hours. When your bacteria are able to convert ammonia and nitrite to nitrate within 24 hours then you can do a big water change.

do you have to do a big water change if it'll be heavily planted?

i think so. the plants (especially some floating ones) do take in nitrate, but i don't think enough to not change the water if you see it's getting close to 40ppm. My tank is pretty heavily planted now and the bacteria are eating ammonia like mad to keep up to the new bioload of ten tetra and 11 shrimp, so it's pumping out nitrates pretty hard. i did a big water change after the fishless cycle when the nitrates got to 40ppm, (ammonia and nitrites 0ppm) but even now with all the plants, the nitrates are at 20ppm what with all the fish and shrimp in a 20 gallon tank (still zero nitrites, but ammonia a little under 0.5 ppm so the bacteria are still eating like mad). I see it go past that, and I change the water 10-20% (with Prime).

I gotcha, I have use RO water so its a pain to do a 80% water change or such. It takes about 8 hours to fill a 40 breeder

your nitrites are still fairly high, and I can't tell what the left tube is testing,, nitrates?

Your cycle will be complete when your ammonia and nitrites are 0, and when you can add ammonia one day, and have it (and nitrites) register as 0 ppm the following day.

Nitrates shouldn't drop to 0 unless you are extremely heavily planted. 0 ammonia, 0 nitrite and readable nitrates is what you want.
