0 ammonia, 0 nitrite, 0 nitrate after 2 weeks?
I've had my 40 gal tank with 5 black neon tetras and 2 pepper corys for 2 weeks now. The fish are doing great, very active and eating. I did loose one tetra 2 days after putting them in the tank. I presume this was because the fish was sick to begin with.
My question relates to the fact that I have yet to detect any ammonia, nitrite, or nitrate. I have a canister filter and plenty of external aeration. I also treated the water with chlorine remover. Is there a good explanation for why I haven't seen any ammonia yet?
