New fish owner here who has spent much $$$ on all sorts of potions for the water. Took the plunge to buy your EcoBio-Block and it made the water crystal clear within three days and normalized the water chemistry in less than a week without doing anything else. We now have a very happy tank with shrimp, snails and fish. I will be buying more and recommending you to others.


I purchased a Medium EcoBio-Stone from you about 4 weeks ago. I was at my wit’s end because I could not get my 29 gal tank to have a crystal clear water. I tried all kinds of water classifiers, bio products, water changes, you name it. Nothing worked as well as I wanted. As a last ditch effort, I went on line and found out about the EcoBio-Stone. I was reluctant because of the price, but decided to give it a try.

Well, the results are nothing short of fantastic. My tank is absolutely beautiful, crystal clear and the fish look extremely healthy. What a great investment!


Had to tell you how amazing your product is. I have a 90-gallon tank with 3 koi and 6 other goldfish, and have had trouble for years maintaining water quality despite having two large filters. I purchased 2 EcoBio-Stone M and within a week, the tank had stabilized, and now the water is crystal-clear.

Awesome product!!
