Fritz Aquatics CopperSafe
Fritz Aquatics CopperSafe sits between premium and economy offerings by combining laboratory-grade copper compounds with clear dosing guidance, giving hobbyists a reliable middle-ground option for ich eradication. Compared to API's cost-first approach and Seachem's high-precision product, Fritz emphasizes purity and consistent performance while often undercutting the highest-end pricing; its technical advantage is consistency of active copper concentration and robust quality control. That balance of performance and value makes it a market-favored choice for hospitals and dedicated hobbyists.

Seachem ParaGuard
Seachem ParaGuard is intentionally included as a non-copper, broad-spectrum alternative for ich treatment when copper is contraindicated (for example, in tanks with invertebrates), offering a different technical approach to parasite control. While not a copper medication, ParaGuard's advantage over copper products is that it allows treatment of mixed-community aquaria without the toxicity concerns copper can present; financially and technically it is comparable to Seachem's Cupramine but serves a distinct use case rather than competing directly on copper efficacy. For aquarists who cannot or prefer not to use copper, ParaGuard is the practical market-leading copper-free option.
