In about a week you should have green water with some infusoria and in about 2 weeks it should be booming
I suppose once you have the green water, and it's booming. Hopefully someone else can help, because I've never attempted it before.

It's difficult to add to Alisa's great answer, but I must try. Once you
have the beasties in your fry tank, it is better to feed the infusoria
there and get them to sustain a population, if you can. This cuts the
chance of introducing a bad bug like hydra, cyclops, dragonfly larvae,

Oleg Kiselev gave me a pure (laboratory) strain of paramecium (slipper
bacillus?) and I have kept them going for many months in cultures and
in baby tanks by feeding them the LiquiFry for egglayers. Water
clearing? Add a couple of drops. Clouds of live stuff in hours. Just
never use a wrong eyedropper and contaminate your culture with

Good luck from me, too, Ken Wright
