Fully cycled already?
I started cycling my tank on the 13th ... today i did my normal water change and tested the water and was shocked to see 0 ammonia, 0 nitrites and 5+ ppm nitrates
however my tests never read any nitrites ... so i am wondering is my tank truly cycled or not
40 gallon - Misc fish
15 gallon - Axolotl
5 gallon - Betta and ADF
20 long - Hatchling turtles and corydoras.
Soon to change I am sure
