I don’t have a tester that says the numbers, just the Tetra liquid that goes yellow if all good.
The fry tank and my male tanks are perfect, it’s just this tank I got from my son. Always seems to be something. I’ve ordered a tester that dose the lot now.
Ok, so I’ll change the water again today. What about the two tanks that’s ok, specially with the seven fry in there, both changed Saturday, still showing fine. When should I changed them, if they stay fine.
Also, the fry tank has some algae in there now, would it be safe to put my Brussel nose in with the fry, Hes about three months old the fry one week.
