Review on 🔍 TetraPond Replacement Pre-Filter Foam for Tetra Water Garden Pump, 1-Inch Diameter (Model: 46798190172) by Jessica Lange

Not only did it work great as a pre-filter, it also kept my fries out of the filter. One of them was enough for two of my power filters. Modification needed... With my Penguin 350 I had to make cuts on the inside to adjust the shape of the filter mesh and with the Whisper 3 filter I had to zip the pre-filter to the mesh as it was too loose. I also had to cut the back of the pre-filter so it was flat and there was space between the power filter downpipe and the glass. Great price and versatile.
