Continuous Hatch 'N Feeder

Hatch brine shrimp (sold separately) continuously in your marine OR freshwater aquarium. Unique design means saltwater in the hatcher never mixes with aquarium water. Hatched shrimp simply swim out into your aquarium by their natural attraction to light, while fish guard keeps hungry mouths out.

Includes: hatcher, 40" of airline tubing, measuring spoon for salt/shrimp eggs, cleaning brush, and holder with suction cup. Measures 2-1/4" x 4-3/4" x 8-1/4" high. Requires a small air pump that will provide between 75-100 l/hr. For freshwater aquariums, the addition of aquarium salt to the Hatchery will be necessary.

• Before setting the Hatchery up, clean it under running warm water. Do not use soap or detergents since it can leave harmful residue. Rinse it well with cold water.
• Connect airline tubing to air pump and Hatch 'N Feeder. Press the suction cup holder firmly against the glass wall of the aquarium.
• Set Hatchery in 79 degree to 81 degree dechlorinated water. (Rate of hatching is temperature dependent, the higher the water temperature the faster the eggs will hatch.)
• Submerge the Hatchery, filling the Hatchery with tank water.
• Be sure the Hatchery is positioned properly. The water level indicator must be level with the surface water.
• Add 4 small spoons of eggs to the egg chamber. Use small end of measuring spoon to measure out the desired amount of eggs.
• Turn air pump on, 3-4 small bubbles per second. It is important to keep the air flow rate low, too high of air flow will cause the eggs to splash against the sides of the hatchery.
• Wait 1 hour for eggs to rehydrate before adding salt to the hatchery.
• Add 5 large spoons of synthetic sea salt or non-iodized table salt to the egg chamber, using the large end of spoon. Synthetic sea salt is recommended because of the buffering abilities.
• Gently swirl any eggs still at surface in egg compartment. Don't worry if eggs remain in collection chamber since they will hatch there also.
• The brine shrimp larvae will start hatching in about 18 to 26 hours depending on the water temperature.
• As the larvae hatch, place a light over the perforated dispenser. The larvae will swim towards the light, since they are phototactic and are drawn to the light.
