A new tank without cycling

Tynk,

I didn't realize this. I am guilty of doing the filter "swish" in the
new tank whenever I change out the media. I've never done it to cycle a
tank but I always thought it would help when I'm replacing the media
bag with a clean one. Go figure.

Also, as for simply squeezing an established filter's media into the
tank and leaving the muck behind and *not* the actual filter pad, you
have not added the nitrifying bacteria to the new tank. The bacteria
secrete a glue like substance and adhere themselves to the surface of
the pad, gravel, tank walls, plants, decor, etc. of the established
tank.
They do not fall off the filter pad when you squeeze it out, nor do
they float about in the water as some people may think.
This sticky substance was found by scientists within like the last 10
yrs.
Many older hobbyists still think you can take the debris or squeeze out
a filter pad and seed a new tank, however, you cannot.
