Overview
Provides zooplankton and fully-digestible, unhatched eggs ranging in size from 50 - 300µm.

Ideally-sized for many stony corals, clams, sponges, tunicates, tube worms, larval crustaceans, juvenile fishes, and adult planktivorous and microinvertebrate-predatory fishes.

Formulated to provide over four-thousand prey per ml.

Does not require refrigeration.

Supplemented with a proprietary amino acid to aid incoloration of invertebrates and fishes.

Formulated by a marine scientist.

Technical Background
Brightwell Aquatics Zooplanktōs-S is a concentrated suspension of phytoplankton-enriched, adult Brachionus sp. (rotifers), their eggs, and the eggs of another group of crustaceans; the result is a food source rich in amino acids, fatty acids including omega-3 HUFAs, vitamins, minerals, and carotenoid pigments giving them a natural, bright yellow appearance. These prey items fall within the microplankton (20.0 - 200.0µm) and mesoplankton (200.0 - 2,000.0µm) classes of plankton. They are the proper size for feeding many species of stony corals (particularly those with short tentacles), as well as clams and other bivalves, sponges, tunicates (sea squirts), plumed worms (Christmas tree worms, feather dusters, etc.), larval crustaceans and bivalves, juvenile fishes, and the adults of planktivorous fishes (such as anthias, basslets, psuedochromids, dartfishes, chromis, etc.) and microinvertebrate-predators (such as mandarinfishes, some gobies, dwarf wrasses, etc.).
Though Zooplanktōs-S provides a number of amino acids, one that is not naturally present has been added; this proprietary amino acid has been shown in studies to increase coloration of corals and other marine invertebrates. Additionally, a small percentage of vitamin-C is present to increase the benefits of Zooplanktōs-S, particularly to corals and their allies that have recently undergone fragmenting or propagation.
Zooplanktōs-S may be used in conjunction with other planktonic suspensions to provide a complete range of sizes to filter-feeding and planktivorous organisms.
Zooplanktōs-S does not require refrigeration, however storage in a cool, shaded area will prolong the activity of the vitamins. Refrigeration will maximize the shelf-life of the product.

Instructions and Guidelines
Shake product well before using. Turn protein skimmer and other forms of mechanical filtration off prior to adding food suspensions to aquaria, and allow 10 - 15 minutes after feeding before resuming operation of filtration.
Target Feeding (recommended): Target feeding may be carried out with a lengthy piece of rigid air tubing, plastic syringe, pipette, dropper, or similar device; pour 5 ml (1 capful) into a small container and suck a portion of this into the feeding device, then slowly discharge the contents of the device 2 - 4" upstream of the target organism(s). Repeat these steps as deemed necessary. Rinse the portion (inside and outside) of the feeder that was placed into aquarium water before placing it into this bottle (if feeding directly from the bottle rather than from a separate container); failure to do so will contaminate the product and encourage it to decompose.
Broadcast Feeding: Add up to 5 ml per 50 gallons of water in the entire aquarium system in an area of rapid water movement daily for the first four weeks of use; thereafter, the dosage may be increased as desired.
Notes: Add no more than 5 ml total of liquid food suspensions per 50 gallons of water in the entire aquarium system daily for the first four weeks of use; thereafter, the dosage may be gradually increased as desired. Starting out at a low dosage and gradually increasing it with time will allow the biological filtration in the aquarium to adjust to the increase in nutrients and prevent water quality from deteriorating.
Planktonic food suspensions (such as this one) are best utilized by target feeding specific invertebrates in an aquarium; in doing so, the majority of the food may be consumed by the intended organisms rather than ending up in filtration media or indirectly impacting water quality (as often occurs when indescriminately "broadcast feeding" by adding liquid food suspensions to a stream of water and allowing the contents to disperse randomly throughout the aquarium system).

Caution:
 Keep out of reach of children. Not for human consumption.
