Review on 🔍 Tetra Stay-Clean Bio-Bag Large Cartridge for Enhanced SEO by Angie Walker

Maybe it's because I have a turtle (which tends to have a harder time keeping the aquarium water clean for a long time). times), but I can't say that these filters differ from standard Tetrabio bag filters. Due to the huge difference in price, I expected a noticeable improvement in the condition of the tank when using them; unfortunately I hardly noticed any changes. I'll go back to the standard version once I use all of this.
