SeaChem Medications

Seachem Cupramine™
Seachem Cupramine ™ Seachem Cupramine ™ effectively eradicates ectoparasite of both freshwater and marine fish. It has all the advantages of copper sulfate and chelated copper, but not the disadvantages. Like copper sulfate, it is fully ionic and effective at low concentrations. The cupric (Cu+2) charge is fully active. Like chelates, it is safe for fish and it is not precipitated in the filter bed. Unlike both, there is more than a 4x concentration gap between the minimal therpeutic dose and the toxic dose. Unlike copper salts, it is stable in the aquarium, and, unlike chelates, it is easily removed by chemical filtration. Unlike other copper products, it is both highly effective and safe in freshwater as well as marine water. It does not damage the filter bed. Cupramine™ contains 10,000 mg/L of copper and 100 mL treats over 500 gallons. Do not use in conjuction with ParaGuard™. Test for copper with our MultTest: Copper™ kit. Marine or freshwater use.

Caution: Turn off your UV sterilizer while treating with Cupramine. UV will break up the ionic bond in Cuprimine; causing it to be much more toxic.

Seachem AquaZole™
Seachem AquaZole ™ Seachem AquaZole ™ is a metronidazole based medication for both freshwater and marine fish. It is effective against Cryptocaryon, Hexamita, and Ichthyophthirius.

Seachem Focus™
Seachem Focus ™ Seachem Focus ™ is an antibacterial polymer for internal infections of fish. It may be used alone or mixed with other medications to make them palatable to fish and greatly reduce the loss of medications to the water through diffusion. It can deliver any medication internally by binding the medication to its polymer structure. The advantage is that the fish can be medicated without contaminating the entire aquarium with medication. Fish find Focus™ appetizing and it may be fed to fish directly or mixed with frozen foods. Focus™ contains nitrofurantoin for internal bacterial infections. Marine and freshwater use.
