Hi All,

I recently set up a small QT , 100 g tank, small outlet in base with a gravity fed small box filter containing a small pump.

I appreciate that using treatments could render the filter useless.

So when I have put fish in the QT, I get ammonia within 24 to 36 hours that's if the reading is correct after adding a treatment.

If I do a water change, the treatment is then diluted.

Should I repeat the treatment?

How do you run your QT?

Regards
