Promising review: "This is THE best stuff ever. My fish LOVE it and it lowers their stress so much so their colors came back and they look so much happier. I have cichlids and color is very important to defining if they are stressed-out or not." –Cheyenne

Promising review: "The pieces I received are excellent! This wood far exceeded my expectations! I soaked them in a bucket for a few days to get the tannins out (completely normal with any wood) and the water was generally clear after the first day. The wood looks great in my office aquarium and I will definitely buy again for my other tank at home!" –Jami

Promising review: "It worked great! I put a fish from the pet store into my aquarium and within a couple of days the new fish died and my old fish had a horrible case of ICK. I bought this product and within 5 days the ICK was gone....completely gone! I read that fish can die within two weeks of first contracting ICK, but my fish look healthy and happy thanks to this product." –TJ
