A few products aquarists come back to often, for treatment, habitat, and water quality.
How to Use Our Fish Products Correctly
Always check the product-specific directions, since dosage depends on a few things.
- Fish species.
- Aquarium volume, in gallons or liters.
- How severe the issue is, whether you're treating or just preventing.
- Whether there are live plants, invertebrates, or corals in the tank.
- Tip: Pull activated carbon out of the filter before adding any medication, or it'll absorb the treatment before it has a chance to work.
What Are the Key Ingredients in Fish Medications?
Formulas vary, but a few active ingredients show up across the collection.
- Erythromycin: A macrolide antibiotic used for gram-positive bacterial infections.
- Malachite Green: A dye-based antifungal and antiparasitic.
- Formalin: Used against external parasites in both freshwater and marine fish.
- Praziquantel: Used to clear flukes and tapeworms.
- Methylene Blue: Treats fungal infections and is also used to protect eggs in breeding tanks.
Are There Any Side Effects or Warnings to Be Aware Of?
- Overdosing can stress or kill fish, so stick to the instructions on the label.
- Some medications can stain decor and silicone.
- Reef and planted tanks may need reef-safe alternatives instead of standard treatments.
- Not every medication is safe for invertebrates like shrimp, snails, and corals.
- Warning: Don't mix medications unless the label specifically says it's fine to do so.
Frequently Asked Questions
Q1: Can I use multiple fish medications at the same time?
Ans: Combining treatments can get risky unless the label specifically says it's fine. Mixing antibiotics like Fix-Mox (Amoxicillin) and Fix-Zole (Metronidazole) can stress fish out or cause interactions you didn't plan for, so it's safer to isolate treatments and follow the dosing instructions for each one separately.
Q2: How long should I keep medicated fish in quarantine?
Ans: Somewhere between 7 and 14 days, depending on the condition and the medication. With something like Fix-Doxy, keep watching the fish during and after the full course, since stopping too early can let the infection come right back or spread to other tank mates.
Q3: Do I need to remove the filter media when using medications?
Ans: Yes, at least the chemical media. Activated carbon will soak up the active ingredients in something like Fix-Flex (Cephalexin) and make the treatment less effective. Mechanical media like WECO Filter Floss doesn't cause that problem, so it can stay put.
Q4: How do feeding blocks like Zoo Med Plankton Banquet affect water quality?
Ans: Used at the recommended size, a slow-release block like the Plankton Banquet Feeding Block shouldn't cause problems. Overdo it, though, and the water can turn cloudy, so keep an eye on your tank parameters and do a partial water change if things start to look off.
Q5: Is it safe to use driftwood like Mopani in all tanks?
Ans: Zoo Med Mopani Wood is generally fine, but it can release tannins that tint the water a tea-like color. If you're after clear water, boil or soak the wood first, since that helps stabilize pH and cuts down on the discoloration.
Q6: Are fish medications safe for shrimp, snails, or other invertebrates?
Ans: Not always. A number of common fish medications, including some antiparasitics and copper-based treatments, are harmful to shrimp, snails, and corals even at normal fish-safe doses. Always check the label for invertebrate warnings before treating a mixed tank, and consider a separate quarantine tank when treatment can't be avoided.
Q7: How do I know if my tank needs a water conditioner like WECO Instant DeChlor?
Ans: If your water comes straight from the tap, it needs conditioning before it goes into your tank. Municipal water systems add chlorine or chloramine to kill bacteria and keep drinking water safe for people, but at those same levels, both compounds are harmful to fish. WECO Instant DeChlor neutralizes both, so treat any tap water first, every time, before adding it to your aquarium.
Q8: What's the difference between mechanical and chemical filter media?
Ans: Mechanical media, like WECO Filter Floss, traps debris and particles as water passes through. Chemical media, like activated carbon, pulls dissolved impurities and odors out of the water. Most healthy setups run both, but pull the chemical media out before you medicate the tank, since it'll strip the medication out too.
