Simply a better buffer. Supplement alkalinity and potassium in one dose.
KATRON delivers more than just alkalinity — it delivers the most overlooked ion in aquatic biology.
Potassium is the ion that drives metabolic processes — from nitrifying bacteria and plant nutrient uptake to fish osmoregulation and enzyme function. Yet it is severely lacking in almost all aquatic systems: freshwater systems rarely supplement it, and saltwater systems assume it is already at adequate levels.
KATRON achieves a higher pH per KH unit than conventional buffers, meaning better alkalinity stability with less pH drift. Ideal for systems that demand precise pH control.
Potassium drives the biological processes that keep your system alive. Every cell in every organism in your tank relies on potassium for enzyme activation, osmoregulation and energy transfer. KATRON delivers it with every dose.
Potassium is almost never deliberately added to aquatic systems. It is not in most salt mixes. It is not in most KH buffers. It is the missing piece in aquatic husbandry — and KATRON addresses it.
Delivers 7.7 ppm bioavailable K+ per dose — the primary driver of metabolic processes across all aquatic life.
Raises KH by 10 ppm with just 1.5 g per 100 L — reliable, measurable buffering action.
Potassium is essential for plant growth and nutrient uptake — one of the three primary macronutrients (NPK).
Purpose-built for recirculating aquaponics systems where potassium supplementation is critical.
Potassium is almost always lacking in saltwater systems — KATRON fills the gap.
Supplements alkalinity while delivering essential potassium for coral and fish metabolism.

Scale proportionally for larger volumes. Actual results may vary with system chemistry.
Standard rate verified on the label: 1.5 g per 100 L raises alkalinity (KH) by 10 ppm as CaCO3 and potassium (K+) by 7.7 ppm. Volumes above are scaled arithmetically from that reference rate.
Approx. 166 standard 100 L doses (250 g / 1.5 g). Ideal for nano and mid-size planted tanks.
Net 250 gApprox. 333 standard 100 L doses (500 g / 1.5 g). The everyday choice for reef and aquaponics keepers.
Net 500 gApprox. 666 standard 100 L doses (1 kg / 1.5 g). Best value for hatchery, retail and commercial systems.
