Product Description
EcoBio-Block Natural Volcanic Rock for Aquarium Water Clarity & Balance — Low-Maintenance Alternative to Weekly Additives — for Freshwater Fish, Turtles, Shrimp & Frogs (Medium 2-Pack, 15-40 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
- MEDIUM 2-PACK — TWO STONES, EACH TREATS 15–40 GALLONS — combine for tanks up to ~80 gallons, treat two aquariums at once, or stagger one in the tank and one in reserve for seamless 2-year replacement; also available as a single Medium, Nano (0.8–1.5 gal), Nano 2-Pack, Mini (3–8 gal), and Small (8–16 gal); for heavily stocked tanks, poor starting conditions, or tanks near the upper end of the range, use both stones together for faster, stronger results
EcoBio-Stones are volcanic rock and cement containing 100% pure beneficial bacteria spores, which effectively clarify cloudy water in aquariums, reducing maintenance. Simply rinse off the EcoBio-Stone, soak overnight and place in aquarium. Using nature's system of purifying water, EcoBio-Stone's beneficial bacteria break down organic waste into ammonia, then into nitrites and then into nitrates, which are processed by vegetation or by anaerobic bacteria changing the nitrates into nitrogen gas, which dissipate into the air. The process of building sufficient amounts of bacteria to take care of the conditions in the average tank, normally results in crystal clear water in 2 to 4 weeks, with a sudden clearing of the water. EcoBio-Stone safely purifies water, eliminates odors and creates a clear and clean environment for fish and other aquatic life. EcoBio-Stone's volcanic stone also leaches back the essential calcium and trace minerals, which are normally returned to water with frequent water changes. This dual action creates a perfect ecosystem. Note: if the water in your tank is very acidic please use EcoBio-Stones after acclimating your fish to pH neutral water by doing water changes.
