EcoBio-Block Aquarium Water Clarifier (Nano 2-Pack, 0.8–1.5 gal ea.)

MORE THAN A ROCK, NOT JUST FILTER MEDIA — engineered with mineral-rich, porous natural volcanic rock, nutrients, and a neutralizing cement binder; the structure absorbs pollutants and stabilizes water chemistry, actively maintaining a stable, healthy tank environment rather than sitting passively like standard filter media

SKIP THE WEEKLY DOSING, LASTS UP TO 2 YEARS — one stone replaces liquid water treatments, clarifiers, and bottled additives for up to 2 years; no droppers, no measuring, no weekly schedule, no recurring costs — just drop it in and let your tank stabilize itself

SIMPLE 3-STEP SETUP, RESULTS IN 2–6 WEEKS — rinse in chlorine-free water, soak overnight in chlorine-free water, then place near your filter outlet or air stone so water circulates through it; most tanks show results in 2–6 weeks, some as fast as 2 days, with slightly cloudy water during the first week being normal as your tank settles in

SAFE FOR ALL FRESHWATER FISH & AQUATIC LIFE — safe for delicate fish, turtles, shrimp, and frogs; ideal for starting a new tank, clearing cloudy water, reducing water changes, and eliminating odors; check pH and standard water test parameters during the first few weeks as conditions settle, and do a partial water change if anything drifts too far

NANO 2-PACK — TWO STONES, EACH TREATS 0.8–1.5 GALLONS — combine for nano tanks up to ~3 gallons, treat two pico aquariums at once, or keep one in the tank and one in reserve for seamless replacement at the 2-year mark; also available as a single Nano, Mini (3–8 gal), Small (8–16 gal), Medium (15–40 gal), and Medium 2-Pack; for heavily stocked tanks, poor starting conditions, or tanks near the upper end of the rang…
