Is 0.25 ppm ammonia bad?

I just tested my water after doing a 50% water change to find I have 0.25 ppm of ammonia (right after the water change was done) and I have 0 nitrates. Is that bad?

 

No since you are still cycling. 0.25 is actually pretty good in a cycling tank. You need to worry if the combination of ammonia and nitrite are equal to or higher than 1. Generally you should wait a couple hours after a water change to ensure the new and old water fully mix. Cycling usually takes 4-8 weeks depending on different situations.

Ok thanks! I made a separate thread because I had a question about a different topic so yeah. I saw someone online saying that if ammonia is above 0 I have to do immediate water change so I got worried. Now that I think about it, I’m not even one month into my water changing schedule so the ammonia should be low but not at 0. Thanks!

That depends. You said you have 0 nitrates. . . What about nitrites?

What do you mean by being a month into your water change schedule? The tank’s been running for a month?

Sorry. It’s one word, I meant nitrites. And by water change schedule, I’ve ramped up my water changes to 50% and have done them weekly since may 21. Before that I was doing 10% every 2 weeks.

 

So how long has the tank been running? And what about nitrates and pH?

What size tank and how many/what type of fish?

I haven’t tested for nitrates, just nitrites and ammonia. I have a 29 gallon tank with 6 guppies. The tank has been running since late February, but I didn’t care about cleaning it until late may (because I learned how to take care of it) since then I’ve been doing 50% WC every week.
