Cardinal tetras - dangerous water parameters?
Hi, I added some cardinal tetras today and did a basic water parameter check of ammonia and nitrite.
Btw, the tank should at LEAST be partially cycled (i hope) seeding it from an established tank.
Anyways, the ammonia I found at 0.4 and nitrite at 0.1. Should I be concerned and do some instant [acronym:3a10d5bbc8="Partial water change"]PWC[/acronym:3a10d5bbc8]? Or should regular [acronym:3a10d5bbc8="Partial water change"]PWC[/acronym:3a10d5bbc8] be ok as long as they stay close or below that level? Thanks.
