{"product_id":"alegi-sponge-filter-pad-20ppi","title":"ALEGI Sponge Filter Pad, 20x20x1 inch, 20PPI, bio filter media","description":"\u003cp\u003eOne sponge filter pad from ALEGI comes in this pack, sized 20x20x1 inch with a 20PPI pore rating and sold as aquarium filter media for a tank's filtration system. The pad is 20 inches square and 1 inch thick, so a filter compartment can take a trimmed piece. Sponge material makes up the pad, and the material resists deformation, decomposition and dissolution.\u003c\/p\u003e\u003ch2\u003eWashing and reusing the sponge pad\u003c\/h2\u003e\u003cp\u003eAfter a wash, the pad can go back into service many times over.\u003c\/p\u003e\u003ch2\u003eWhat the 20PPI sponge does in a filter\u003c\/h2\u003e\u003cp\u003eThe high-density sponge structure provides mechanical filtration, and particles held in the water are captured by the pad. ALEGI states 20PPI as the pore grade for the whole sheet, so the pad is a single density rather than a mix. A cut piece can be placed into the filtration system when the compartment is smaller than 20 by 20 inches.\u003c\/p\u003e\u003cp\u003eBecause the material resists deformation, decomposition and dissolution, a pad that sits in water and gets squeezed out between uses holds its shape.\u003c\/p\u003e\u003ch2\u003eDoes this 20PPI pad suit your filter compartment?\u003c\/h2\u003e\u003cp\u003eCheck the inside dimensions of the compartment before cutting: the pad is 20x20x1 inch, so a space narrower or shorter than 20 inches takes a trimmed piece, and a compartment deeper than 1 inch takes more than one layer of the same sheet. Measure the slot depth as well as its width and length. Trimming decides how much of the 20x20 inch sheet a single job uses, and a smaller compartment simply takes a smaller piece.\u003c\/p\u003e\u003ch2\u003eCutting the pad to size and placing it\u003c\/h2\u003e\u003cp\u003eCut the sheet to the size the filter needs, then place the cut piece into the filtration system. Trimming from the edge of the 20x20 inch sheet leaves the rest of the pad whole for another fitting, and the 1 inch thickness keeps the same depth after a trim. When the pad is washed and reused, the same cut piece goes back into the compartment.\u003c\/p\u003e\u003ch2\u003eWhat arrives with this sponge sheet\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOne sponge filter pad, 20x20x1 inch\u003c\/li\u003e\n\u003cli\u003ePore rating of 20PPI across the sheet\u003c\/li\u003e\n\u003cli\u003eSponge material that resists deformation, decomposition and dissolution\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuestions about this sponge filter pad\u003c\/h2\u003e\u003ch3\u003eHow big is the pad before cutting?\u003c\/h3\u003e\u003cp\u003eThe sheet measures 20x20x1 inch, so it is 20 inches long, 20 inches wide and 1 inch thick.\u003c\/p\u003e\u003ch3\u003eWhat does the 20PPI rating mean on this pad?\u003c\/h3\u003e\u003cp\u003eALEGI lists the pad at 20PPI, a pore rating given for the whole sheet.\u003c\/p\u003e\u003ch3\u003eCan the pad be trimmed to fit a smaller filter?\u003c\/h3\u003e\u003cp\u003eYes.
