    Overview ParaGuard™ is the only fish- and filter-safe aldehyde-based parasite control solution (10% by weight) available for treating external fish infections. Unlike traditional medications containing toxic formalin, formaldehyde, or methanol, ParaGuard™ is safer to dose and will not alter aquarium pH or harm biological filtration. This proprietary formula combines aldehydes, malachite green, and fish-protective polymers to effectively eradicate ectoparasites such as Ich, Velvet, and Flukes, while also addressing external bacterial, fungal, and viral lesions including fin rot. ParaGuard™ is especially effective for hospital tanks, receiving tanks, and during the introduction of new fish to prevent outbreaks. Key Features Safer Alternative – Contains no formaldehyde, formalin, or methanol. Broad Spectrum Treatment – Targets parasites, fungus, bacteria, and viral lesions. Bio-Filter Safe – Will not disrupt your aquarium’s beneficial bacteria. Versatile Use – Ideal for freshwater and marine aquariums. Preventative Option – Excellent for quarantine setups and acclimation tanks. Indications ParaGuard™ is appropriate for treating a variety of parasitic infections in exotic fish, including but not limited to: Ich (White Spot Disease) – Ichthyophthirius (freshwater) / Cryptocaryon (saltwater). Velvet – Gold or rust-colored dust on skin and fins. Fin Rot – Ragged, disintegrating fins. Flukes – Gill or body parasites causing irritation, flashing, and rapid breathing. Suggested Treatment Periods Freshwater: 14 days Saltwater: Up to 28 days ⚠ Important Note: Always complete the full treatment period without interruption. Stopping too early allows parasites to multiply and reinfect fish. Directions Dose 5 mL per 40 L (10 US gallons) daily until symptoms clear or for the full recommended treatment period. For best results, use in a quarantine or hospital tank to avoid reinfection. Do not mix with other medications unless directed.

    Pond Flourish Iron™ - Advanced Iron Supplement for Aquatic Plants Overview:Iron is essential for plant health, particularly in the production of chlorophyll. Since iron is immobile within plants, deficiency symptoms like chlorosis (yellowing) and stunted growth appear first on younger leaves. Pond Flourish Iron™ addresses these issues with a highly concentrated ferrous iron gluconate formula (10,000 mg/L), ensuring optimal plant absorption without unnecessary energy expenditure. Unlike competing products that use ferric iron (iron-EDTA), Pond Flourish Iron™ provides ferrous iron, which remains soluble and readily available to plants across a wide pH range. This allows plants to benefit immediately without needing to expend energy converting ferric iron to a usable form. Additionally, ferrous gluconate supplies a source of carbon, further supporting plant health. Key Features: Readily Absorbed Iron: Provides ferrous iron gluconate, which is soluble and immediately available for plant uptake. Highly Concentrated: Delivers a potent dose of 10,000 mg/L ferrous iron. Energy Efficient: Eliminates the need for plants to expend energy reducing ferric iron. Safe & Effective: Non-harmful to plants and fish, unlike misleading claims about gluconate. Carbon Source: Ferrous gluconate supplies beneficial carbon for plant growth. No Precipitation Issues: Stays soluble across typical pond pH ranges, unlike ferric iron which precipitates above pH 5.5. Sizes Available:500 mL, 1 L, 2 L, 4 L, 20 L
