„I would like to give you a report.
The treatment is finished. It seems to have been successful. Although I had stored all the filter material separately, there was a massive nitrite peak a short time after „reinstallation“, which I got under control with water changes and BACTOSPRINT without any losses. The water smelled very “rotten” for a while after the treatment. I couldn’t find a reason. It’s gone again.
No snail or other invertebrate died during the treatment. I didn’t take them out of the aquarium.
I am happy.
Many Thanks.“
