Uncycled Tank Is Getting Worse

[Macko1968]

Last week I detected 0.25ppm of amonia in my cycled Juwel Trigon 190.

I've cut back the feeding regime & started testing every 12 hours & I added a complete mature sponge from my Eheim 2224. Trouble is, it's getting progressively worse. Initialy I was finding the amonia rising to 0.25 in 24 hours, today (9 days later) it's rising to 0.25 - 0.5 in 12 hours.

I'm at a complete loss as to why it's getting worse & worse, I have no live plants in the tank, stocking is as per my sig & I've accounted for all my fish so no dead ones laying around. My water changes are fully dechlorinated with Aqua One conditioner (stopped using Prime after suggestions it could be causing a false reading) & I know the API kit is sound as my other tank tests perfect.

Can anyone give me any pointers on what it could be that is causing this problem?

cheers

Do you preform a gravel vac when you do a water change.
Do you remove ornaments to hoover the debris.
Whats your tap ammonia reading.

I've been using the vac on a morning & straight syphon on an evening, I move the ornaments when I vac. Out of the tap I'm 0ppm for ammonia.

I would post in tropical discussion to see if members can find out why you have ammonia reading.
Just copy and paste your thread.
Good Luck.
