.25ppm Ammonia for weeks...HELP!!

Can't seem to get ammonia levels to 0ppm. It's been .25ppm for the past few weeks. I've done multiple 50% water changes but still .25ppm. All my life stock is alive and seem healthy. I know for a fact it's not my testing equipment.

Any ideas on whats going on and how can I lower the ammonia?

How do u know not testing kit? Have u compared to another test kit or manufacture? Are u testing properly, some tests require u to time the test and hold a certain distance from scale to determin your results. What are you water perameters and what size tank and what's your livestock?

how long has the tank been up and running, is it cycled or going thru a cycle, if it is cycling there should be not live stock in there, you cycle will take 6-8 weeks

I'm having the same readings. I'm using API test kit and having same reading even though after a 30% pwc. I had to bring a water sample to my fav LFS and he reads 0 Ammonia. Planning to change to a diff test kit...just dont know yet which one.

I had the same issue, but I found out it was my API test kit. .25 ammonia always. Then. I took my water to myLFS and it was fine. Maybe its because its kinda hard to read accurately . But if you still have the same issue take it to you LFS

How long has the tank been running?
Have you tested your tap?
Have you done a major cleaning lately (filters, big gravel vac) ?
What are your other readings for nitrite and nitrate?

I agree with the suggestion to take a water sample to your lfs. Sometimes it is hard to distinguish the difference between .25 and zero on your test kit, and the lfs might clear it up.

If its staying at. 25 after water changes its more than likely your tap water. .25 isn't toxic. Hold off on pwcs for a few days to see if it zeroes. Also test your tap for ammonia

I find more often than not the API test kits yield a "false positive" of .25ppm. I would confirm with a kit of a different make, and then just use .25 as your 0 point.

I would do some water test results on your PWC water. It could be that you are adding the ammonia through your PWC`s. Do an ammonia test on your PWC water to be sure.
