This may be not be the norm with Amazonia, but I have setup 2 new tanks with it over the past 7 weeks and have not had any ammonia spikes but have had a high Nitrite spike in both tanks. One tank is 7 weeks old and the other tank is 1 week old tomorrow. I planted both tanks heavily at the start, they both have CO2, high light and I dose EI. So far, no algae. The Nitrite spike lasted a little over 2 weeks in the 7 week old tank and I did 3 water changes a week for the first 2 weeks. The 1 week old tank is not going to get but 1 water change a week and I will see if that affects how long the Nitrite spike lasts.
Anyway, this has been my experience with 2 tanks. YMMV. BTW, I used 2 different ammonia detection tests on each tank, the Seachem Ammonia Alert and Aquarium Pharmaceuticals Ammonia test kit. Nitrite testing was also with 2 different test kits.
