- Removes chloramines, chlorine, ammonia, and nitrites present in tap water and/or aquarium water.
- May be used to neutralize iodine in the event of an aquarium overdose.
- Used as directed, is safe for use directly in all marine and freshwater aquaria.
- Free of phosphate and silicate.
- Formulated by a marine scientist.
Er?se-Cl immediately binds iodine in the event of an overdose (typified by “drooping” and rapidly decaying tissue of corals, clams, their allies, and other sessile invertebrates, as well as erratic behavior and/or death of fishes and motile invertebrates), decreasing the potential for damage to livestock and the beneficial microbes that constitute the biological filter.
Note: It is strongly recommended that hobbyists administering Lugol’s-type iodine supplements (which are typically extremely strong) to reef aquaria have a bottle of Er?se-Cl on hand at all times, in case of accidental overdose.
To Treat Aquarium Water: Determine ammonia concentration in aquarium using an accurate ammonia test kit with ammonia salicylate reagent (see comments below). Add 5 ml (1 capful) per 50 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 Er?se-Cl.
To Treat Free Iodine Overdose: If you suspect that iodine has been overdosed in an aquarium (such as due to accidental misuse), add 10 ml (2 capfuls) Er?se-Cl per 40 US-gallons in an area of energetic water flow; doing so will neutralize free iodine (i.e. that which is not in an ionic form, such as iodide or iodate, or in a bound form). Observe aquarium livestock for no less than 15 minutes thereafter. Er?se-Cl binds iodine at a rate that is limited only by the response time and degree of water circulation in the aquarium; the faster the product is added after an overdose and the more rapid the water circulation in the system, the better the product will perform. No claim is made that this product will prevent damage or reverse that which has already been suffered by livestock or biological filtration in any event. This product is particularly useful for hobbyists who are experimenting with Lugol’s Solution and other strong iodine sources in an attempt to benefit aquarium inhabitants. Do not exceed a total iodine concentration of 0.10 ppm in a marine aquarium at any time.
