Fish Products FAQs 

Can I use multiple fish medications at the same time?

Combining treatments can be risky unless specifically directed. Mixing antibiotics like Fix-Mox (Amoxicillin) and Fix-Zole (Metronidazole) may cause stress or chemical interactions—always isolate treatments and consult dosing instructions.

How long should I keep medicated fish in quarantine?

Quarantine treated fish for 7–14 days based on the condition and medication used. For example, with Fix-Doxy, observe fish during and after the full course to prevent reinfection and cross-contamination.

Do I need to remove the filter media when using medications?

Yes, remove chemical media like activated carbon when treating with products such as Fix-Flex (Cephalexin), as it may absorb the active ingredients and reduce efficacy. Mechanical media like WECO Filter Floss can stay in place.

How do feeding blocks like Zoo Med Plankton Banquet affect water quality?

Slow-release blocks like the Plankton Banquet Feeding Block are safe if used in recommended sizes. Overuse can lead to cloudy water—monitor tank parameters during use and perform partial water changes as needed.

Is it safe to use driftwood like Mopani in all tanks?

Natural decor like the Zoo Med Mopani Wood is generally safe but may release tannins that tint water. Boil or pre-soak before adding to stabilize pH levels and reduce discoloration in clearwater tanks.
