none of your tanks even sound remotely cycled, have you read the beginners section on here about filter cycling? Im amazed nothing has dropped dead yet.
Do you have a liquid test kit to even read the ammonia and nitrite levels in the tanks?
I had no idea about cycling tanks at first never even came across it when i did some resaerh on starting up a tank.
Though i set it all up and let it run with no fish for a month
then tested it.
added the tetra and one guppy, left it a week and tested it again.
Added 2 gourami left it a week and tested it once more.
It worked fine for me doing it that way
though i wish i had found this site before i started it
