Eek Ammonia wont go down

ok, so i set up my new system about a month ago. and its inbetween mild and heavily planted with stem plants.( which are growing well) im waiting and waiting, for it to finish cycling. the ammonia has been at about 7.5 ppm for the past week and a half. I did a water change and it came right back up.... am I doing soemthing wrong? it dosent seem to be going down at all.

i even put my bio wheel floating around in the tank from my established tank to see if it would help bring the ammonia down but dosent seem to help.

its CO2 injected. at about 1.5 bpm
and the only fish i have in there are 2 otos and a cherry barb, they seem to be ok with all that ammonia..
im quite puzzled

i use the " Fresh Lab" test kit by red sea.

Here is a link that I think might help you. It is very informative.

Ammonia and test kits are not always correct. Something to do with PH and temp.
I hope this helps.

You should look at the bag the substrate material came in to make sure it does not contain any form of fertilizers. If it contains urea, which it may, it will always be a problem for you.

Thats a good point.

Also if you are using prime or something similar it can mess with ammonia tests.

If it was Schultz Aquatic Soil, apparently they started adding little blue fert balls to their substrate not long ago, which would definitely explain those ammonia levels.

At this point, I think daily water changes are in order till you can finally bring those levels down.

Well, either your test kit is wrong or there's some serious organics in that soil... and I'm going to lean towards "all-natural" meaning that there's some organic content. 7.5ppm is pretty high.

Based on this, http://www.pondcare.com/Products/Tec...TechSheetID=16, there are no fertilizers or other organic materials in the substrate material. I notice that the fish were not bothered by the high ammonia, so I suspect it doesn't exist. The test kit is probably incorrect. It doesn't take much ammonia to bother fish.
