So Im on the 3rd day of cycling my 3 gallon Pico. I decided to go with the shrimp method as my ammonia source. When I tested today, ammonia was 1.0 ppm and nitrites 0.50 ppm. I took the shrimp out because I was worried that in such a small tank I would accidentally overdo the ammonia. Should I raise it even higher? Also do Pico tanks cycle faster than bigger tanks?
