Shrimp Prep may be used to prepare water for use in aquaria (such as when performing water changes or replacing water lost to evaporation), as well as during periods of time when the concentration(s) of ammonia and/or nitrite become measurable (ammonia and nitrite concentrations should remain immeasurable in established aquaria with mature biological filtration, except for periods when new livestock are added to the system or the concentration of dissolved organic material has increased for some reason).
Shrimp Prep is not meant to be considered a substitute for maintaining adequate filtration equipment/methods or the care thereof, however it can be utilized as needed in the prevention of ammonia or nitrite from irritating sensitive aquarium inhabitants. A balanced aquarium is one in which the rate of organic material input to the system is matched by the removal rate from filtration methods; it is natural for a system to become unbalanced for short periods of time after adding new livestock, disturbing the biological filtration, changing feeding habits, etc., however the system should fall back into balance again within a period of days.
If concentrations of ammonia or nitrite are persistently-measurable with a quality test kit, test the source water (i.e. tap water or water from the purification unit (if applicable)) for these substances. If they are not present, reducing the rate of organic material input, increasing the filtration capacity, or even moving the inhabitants into a larger system may be warranted. Chronic levels of ammonia and nitrite can gradually weaken fish, shrimp and other invertebrates, often leading to illness and potentially death.
To Treat Tap Water for immediate aquarium use: Add 4 ml (2 pumps if equipped with pump) of this product per 8 US-gallons (30 L) of aquarium water; this corresponds to 5 ml or one capful (if not equipped with pump) or ~35 drops per 10 US-gallons (38L). When used in this fashion, 500 ml treats up to 1,000 US-gallons (3,800 L). Shrimp Prep will treat up to 6 ppm chlorine, 3 ppm chloramines, or 1 ppm ammonia, and detoxify heavy metals.
To Treat Aquarium Water in emergencies: Determine ammonia concentration in aquarium using an accurate ammonia test kit with ammonia salicylate reagent (see comments below). Add 4 ml (2 pumps if equipped with a pump) per 8 US-gallons of water in overall system per 1 ppm of ammonia measured on test kit. Allow 10 minutes to elapse, then re-test ammonia concentration in aquarium and repeat treatment instructions if necessary.
Testing for Ammonia: When using this product, be sure to measure ammonia with a test kit featuring ammonia salicylate reagent rather than Nessler’s reagent; Nessler’s reagent will give an incorrect positive reading of ammonia due to the manner in which the reagent interacts with the active components of Shrimp Prep.
