This is a simple yet very effective way to tumble eggs or to aid with the fry that are at a mere Head & Tail size when stripped.
I have used this method for several years and have found the success rate to be excellent as long as the system is constructed and prepared correctly.COMPONENTS
1 x length of hose [this is made into a float loop to help support the sieve at the correct height]
1 x Plastic Flour Seive [available from Bi-Lo etc for a couple of dollars]
1 x medium sized airstone with suitable length of air line and a regulator attached
1 x Suction Cap as used for heaters etc.
1 x suitable tank to act as both the housing for the egg tumbler and the initial grow tank for the fry.
1 x Bio-Sponge Filter [I have found these also provide an initial source of food for the developing fry]
1 x GOLF BALLOptional:
Place the sieve [with or without the handle removed] under a staedy flow of HOT water.
Gently but firmly press the golf ball into the lowest section of the sieve whilst it is still hot and form a 'Dimple', this aids with the movement of the eggs and helps to prevent them becoming attached to the sieve. It also aids to ensure the eggs remain clear of fungus etc.
Set up the sponge filter, airstone, airlines and taps etc.
Attach the sieve to the wall of the tank via the suction cap and hoop.
Fill the tank to the desired depth with pre-aged and conditioned water [I have also had success using water from the original spawning tank]
Ensure that the airstone is positioned directly below the centre of the sieve and adjust the bubble rate to a steady but NOT hard flow rate.
Transfer the eggs from their container into the sieve [being sure as to not allow them to come into contact with the air to help avoid the chances of contamination]
Adjust the airflow rate so that the eggs are GENTLY moving around in the sieve [this prevents the eggs from being damaged during the incubation/tumbling period.NOTE:
It is vitally important to be sure to remove any fungus eggs ASAP to prevent the spread to viable eggs.
Once the fry have developed to a suitable size it is a simple matter to allow the sieve to lower into the tank and thereby introduce the fry to the fact of moving from the sieve.
I hope this helps
