Hi Guys, i collected my data and set up a little Diagram.
On the left side, you can see a yellow bar, its the day when i added my fish to the system.
The green bar is the day where i added my plants and the red bar is the day where nitrate was at its peak (40ppm). I cycled with ammonium hydroxide (initially 5ppm) and due to the warm climate and starter bacterias, i was able to find nitrate after 6 days and ammonia and nitrite went to 0ppm. At that day 20 i added my fish. At day 27 i added my plants. I hope its helpful. Cheerio
