Penn Plax AS4 Aqua Stones Review

The Penn Plax Aqua Stones add the perfect touch of elegance to my aquarium. The stones come in a variety of sizes and colors which makes arranging them so much fun! According to my experience, these stones do not affect the water quality and are safe for my fish. The only downside is that they are a little pricey compared to other aquarium decorations. Overall, I would recommend these Aqua Stones for anyone looking to enhance their aquarium's aesthetic. As someone who regularly buys pet…

Heed Other Reviewer's Warning I didn't think I was lucky, but no. This will dissolve in your tank and your fish can eat it and get sick. It was already dissolving when I received it in the packaging. I figured I could use it by wiping and rinsing off the loose bits, but the more I touched it the more it crumbled. stay away

Does not seem safe. I didn't use it very often because I didn't need it. When it came out of the box I noticed that it was a little crumbly(?) like it was made of the thinnest material and when I was only using it for testing in clear water some small pieces continued to crumble with bubbles. I don't think this product is very safe for anything and I would recommend using a different product (maybe a different brand?). I generously gave two stars because the blisters seemed permanent.
