26 gallon AIO landen 60P. 20lbs dry rock & live sand. Started cycle with Microbacter7, dosing at recommended ml for 4 days now. Added quickcyle ammonia day 1. API test kit measuring ammonia at 1ppm and nitrites at 0ppm. I decided to add Microbacter start xlm on day 3. . . Did I make a mistake mixing the two bacteria? Also when can I expect to see nitrites?
