About Mardel Coppersafe®

Mardel Coppersafe® solution remains active for over one month in the aquarium. It is a safe, stable, non-staining concentrate that does not color aquarium water.

Be sure to add Mardel Coppersafe® solution to replacement water when water changes are made. This will maintain the therapeutic level of Coppersafe® solution.

Because Mardel Coppersafe® solution is so stable in water, partial water changes are the quickest way to remove it from the water.

The unique formulation of Mardel Coppersafe® solution maintains a total copper level of  ~2.0ppm when used as directed. Copper test kits that measure chelated copper will help you to actively monitor copper levels when using Mardel Coppersafe® solution.

FAQs

FAQs

See below for frequently asked questions regarding Mardel Coppersafe®.

  • What is the therapeutic range for copper in an aquarium?

    The therapeutic range of copper is 1.5ppm - 2.0ppm. Some test kits have different scales so be sure to contact the manufacturer of the test kit if you have questions!

  • Can I use Quick Cure and Coppersafe together to treat Ich? Is Coppersafe suitable as an Ich preventative?

    I have both of these products and noticed an out break of ich in one of my tanks and had recently moved fish from that tank to two other tanks. Im treating the tank with the obvious ich with quickcure and put coppersafe in the other tanks as a preventative. Is this correct? Can I use both products at the same time? Does the quickcure kill ick at all stages of its life cycle? or should you treat for longer than 2-3 days.

     

    What you are doing is the best course of action. While both products are effective at controlling Ich, Quick Cure is the more aggressive treatment and is the best choice to handle the quickest. You are correct that Coppersafe can be used as a preventative.

    The Ich life cycle is five days, so I recommend leaving medication in for that time period.  Raising the temp of the aquarium will help speed up the process as well.

  • Do I add Coppersafe to top off water during treatment?

    I've been using Coppersafe in a 5 gallon tank for 1 betta that appears to have Velvet disease. I initially dosed 3/4 teaspoon on then topped off the tank with 1 gallon treated with 1/4 teaspoon. Should I keep dosing the tank in incremental amounts as water evaporates or give it more time to work? The tank is heated to 80 degrees F and I'm running a corner bubbler filter. I have live plants and used Seachem's Aquasolum substrate.

    You should not be adding more coppersafe to evaporated water, as the copper will not evaporate. Only add Coppersafe to water you are replacing.

  • Can I use hydrogen peroxide as a spot algae treatment while treating the aquarium with Fritz Mardel Coppersafe®?

    No. The complex copper in Mardel Coppersafe® will impact the hydrogen peroxide, making it ineffective against algae. It is not clear if the Mardel Coppersafe® is affected in the process so we cannot recommend using the two together.

  • After your first treatment with Mardel Coppersafe®, how long do you have to wait to do a water change?

    Unless you observe stress in the fish, you should not do a water change for a month. That is because the chelated copper stays in solution for that period of time which covers the life cycle of almost all aquarium parasites. This ensures that any eggs in the aquarium will hatch out and the parasites will be eliminated.

    If your animals are stressed, a water change may be necessary. You will need to dose the replacement water at the label dosage so that the copper remains at an effective level. Copper test kits are recommended to monitor levels in the aquarium.

  • I’m having trouble working out the dosage of Mardel Coppersafe® because I have a lot of rock in my tank and I’m not sure of my sump volume. Can you help?

    Because copper can be toxic when it is overdosed, you should be conservative with your estimates of water volume. There are many online calculators which can help you determine the volume of any rectangular sump. Use a test kit to measure copper levels and if they need to be increased, do so carefully.

  • Are there any animals that are sensitive to copper that I should be careful with Mardel Coppersafe®?

    Lionfish, pufferfish, mandarins, blennies, eels and any other scaleless fish should be treated with care. Watch for adverse reactions to the copper and be prepared to do water changes. You can also use carbon and specific copper-removing filter media to rapidly remove the copper from the water.

    Of course, as indicated on the directions, Mardel Coppersafe® should not be used with invertebrates of any kind and should be removed from the water before returning invertebrates to the aquarium.

  • How often do I need to dose Mardel Coppersafe®?

    Mardel Coppersafe® is a chelated copper solution which will keep the copper active in the aquarium for up to a month. You should use a test kit to monitor copper levels.
