QT filter takes 3 days to process 2 ppm ammonia

[Muffin87]

My 20G QT filter takes 3 days to process 2 ppm ammonia. I've added 2 ppm three times so far (checked w/ Hanna Ammonia checker).
Should avoid adding fish to this QT tank until I can get the tank to process 2 ppm ammonia in 24 hrs?


Filter:Tunze 3163 filter suitable for tanks up to 45G. It's filled with siporax mini, and siporax pond 25mm.
Will add a sponge filter from DT.

Thats a pretty good rate.
