We are cycling a 300 gallon setup with sump. We set the tank up 15 days ago, running pumps and powerheads at full speed - high temperature in tank. 14 days ago I added ammonia to approx 5 ppm and added some filtermedia from an existing tank (only a little). Since then I have also added a few shimp in the sump and some fishfood.
I have tested for ammonia, nitrite and nitrate daily since then - consistently getting high ammonia, no nitrite and no nitrate. I have read that the expected time for nitrite to appear should be 8-10 days (without the added filtermedia). I performed a patrial waterchange 3 days ago bringing ammonia to 4-5 ppm. My measuring scale stops at 5 - and I didn't want it too high.
Are we doing something wrong or is it just a matter of waiting it out?
