I had tried everything the internet and the local fish stores said to do. Nothing worked. Added the Rock to the tank on 7/22. It took about a week before there was a massive difference but I could see a small one daily. Tank has been crystal clear for more than a week now. No chemicals. No water change. I did add a new bubble disc under the rock. Review: Clear waters - It works! I set up a goldfish aquarium and little did I know all the research I should have done beforehand. My aquarium was cloudy for about 2 weeks and nothing was clearing it, even the brand new filter system I set up with Seachem Stability live bacteria I was adding each day. This rock randomly came up in my search and the one review that shows before and after was the reason I bought it. You need to soak it overnight in tank water or tank safe water. Once added, my fish tank slowly started to clear a little each day and by day 5, crystal clear. I’m thrilled! ## Features - MORE THAN A ROCK, NOT JUST FILTER MEDIA β€” 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 β€” 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 β€” just drop it in and let your tank stabilize itself - SIMPLE 3-STEP SETUP, RESULTS IN 2–6 WEEKS β€” 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 β€” 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 - SMALL SIZE TREATS 8–16 GALLONS β€” sized for 10- and 15-gallon community tanks, planted aquascapes, and small freshwater setups; also available in Nano (0.8–1.5 gal), Nano 2-Pack, Mini (3–8 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003SOO4XY | | Allergen Information | Allergen-Free | | Best Sellers Rank | #9,715 in Pet Supplies ( See Top 100 in Pet Supplies ) #61 in Aquarium Water Treatments | | Brand | EcoBio-Block | | Brand Name | EcoBio-Block | | Customer Reviews | 4.2 out of 5 stars 4,239 Reviews | | Global Trade Identification Number | 00897819001065 | | Included Components | EcoBio-Stone S | | Item Form | Brick | | Item Type Name | Natural water clarifier | | Item Weight | 6.08 ounces | | Liquid Volume | 16 gallons | | Manufacturer | ONEdersave Products LLC | | Manufacturer Part Number | EBSSC00106 | | Model Number | EBSSC00106 | | Number of Items | 1 | | Number of Packs | 1 | | Pet Type | Amphibian, Fish, Reptile | | Target Species | Fish, Reptile | | UPC | 897819001065 | | Unit Count | 1 Count | | Warranty Description | 120 day satisfaction | ## Images ![- EcoBio-Block Aquarium Water Clarifier (Small, 8–16 gal) - Image 1](https://m.media-amazon.com/images/I/611BUkvskaL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than I thought it would be! *by A***L on August 10, 2026* I was skeptical.
