How to culture infusoria to feed to your fry

How to culture infusoria to feed to your fry.

Here are the following materials you only need.

1) Base Jar
2) Lettuce leaves
3) System water

Steps to follow.

1) I use a 350ml clear base jar (or depending on how many fries your feeding, you could use bigger jar).
2) Fill the jar with system water up to the neck.
3) Wait for the next 3-5 days. Between that time, the water will turn green then cloudy and finally it will stay clear.
4) You could use a magnifying glass or zoomed-in media device (cellphones, camera's) through a lighted background just to see these small infusoria's.
5.) Don't forget at least to shake the jar once or twice a day to keep the water well aerated on a closed jar.

Thank You for watching!
