"If the ammonia is under 0.25 then you are okay. If it's between 0.25 & 0.5 then carry out a sizable water change, I would say no more than 50%. If your ammonia is very high, 1.0 and above, carry out a very large water change, 75%, 80%. Many people do a water test directly after the water change. Sometimes you can get false readings doing it this way so always carry out your water tests before your water change. It's not worth panicking about, your water change should remove the ammonia so don't worry."
I just started cycling my new 70L aquarium with 6 neon tetras. Ammonia levels yesterday were 0.25ppm, today they were 0ppm. Nitrite on both days is 0ppm. Nitrate today was between 1-4ppm. (I used filter media from an established tank)
So, if the ammonia levels are between 0.25 & 0.5ppm, should I do a huge 50% water change? I always thought it was 20-30%. My tanks only had fish in it for 2 days.
