API Aquarium Salt is a pure salt product commonly used as a supportive, non-chemical therapy for ich and general parasite stress. It earns a best-in-class spot for salt-based treatment because it is inexpensive, widely available, and gentle on fish when used correctly, making it a cost-effective first-line or adjunct option compared with pricier medicated remedies like ParaGuard or Ich-Attack. While not a silver-bullet in severe infections, its technical advantage is simplicity and safety in fish-only tanks where copper or stronger chemicals would be inappropriate.

The Fluval M Series is positioned as the premium, digitally controlled heater in this group — it offers precise temperature control, a slim profile, and rapid recovery that make it well suited to sustained elevated-temperature Ich treatment protocols where tight setpoint stability matters. Compared with the more mechanical Eheim or budget Aqueon, the M Series trades a higher purchase price for a clearer display, programmable features and faster response; when paired with an external controller like the Inkbird it delivers industry-leading accuracy and safety for critical heat cycles.

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.

Kordon Ich-Attack earns a spot as a market leader for targeted ich control within formalin-free regimens because of its longstanding reputation among breeders and quarantine specialists for consistent performance. It strikes a middle ground between strong efficacy and fish safety, making it a go-to when treating display or hospital tanks without resorting to formalin or copper-only approaches. In comparison to broad-spectrum concentrates and economy brands, Kordon is often chosen for its balance of predictability and fewer compatibility trade-offs with delicate species.

The Marina Floating Thermometer with Suction Cup is a low-cost, dependable temperature monitor that retains market favor for basic aquarium temperature checks essential to Ich management, since temperature affects parasite lifecycle and treatment timing. It lacks the precision of digital thermometers and the salinity measurement of products like Fluval or Hanna, but its affordability and simplicity make it a practical staple for everyday monitoring during dosing protocols.
