EcoBio-Block Natural Volcanic Rock for Aquarium Water Clarity & Balance — Low-Maintenance Alternative to Weekly Additives — for Freshwater Fish, Turtles, Shrimp & Frogs (Nano, 0.8-1.5 gal) - size: 1 Pack, style: Nano

About this item

• 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 SIZE TREATS 0.8–1.5 GALLONS — sized for pico tanks, desktop bowls, single-betta cubes, and the smallest nano shrimp setups; also available in Nano 2-Pack, 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 range, choose the next size up or add a second stone for faster, stronger results
