Ultimate 16oz

$ 49.00 until FREE shipping

Ultimate is a dechlorinator that has aloe in it. Great for helping repair the slime coat on your fish. Each 16oz bottle treats 940 gallons of water. It also helps buffer your water from changing pH.



To fully condition water for (1) new aquariums or ponds (2) after or during water additions, or (3) before adding new fishes, amphibians, invertebrates or plants, add 1 teaspoonful (5 mL) of Ultimate per 10 gallons of water. For larger applications use the following dosage: 1 oz. per 60 gallons of water.


®ClorAm-X, electrolytes, buffers and a proprietary polymer formula in aqueous solution.
Recommendations: Perform regular water changes to keep the alkalinity (acid-nuetralizing capacity) and pH stable. Use ®Ultimate as needed to eliminate and control ammonia at the regular dosage rate for each 1 mg/L, or fraction therefore of measured total ammonia or for each 0.85 mg/L of measured total ammonia-nitrogen. Use a salicylate (indolphenol) type total ammonia test kit. For dissolved-oxygen (DO) testing use either a DO meter or an indigocarmine test. Maybe used at the regular dosage to stop or destroy permanganate treatments.
Contraindications: Do not use with permanganate-based or chlorite-based treatments. Nessler’s total ammonia test will give false, high (or off scale) readings. Winkler dissolved oxygen tests will give false, low (or zero) readings.

Great stuff

Works great as a water conditioner and is safe for use with ICH-X due to being a non sulkfinate/sulfoxylate based water conditioner (unlike prime).

Excellent product
