{"product_id":"pawfly-pre-filter-sponge-12-pack","title":"Pawfly Pre-filter Sponge Filter Media, 12 Pack, 0.8\" intake sponge foam","description":"\u003cp\u003eTwelve pre-filter sponges come in this pack, each measuring 3.4\" long and 2\" across with a 0.83\" hole through the middle. The sponge slides onto the water inlet of a fish tank filter, where it keeps shrimp, fish fry and weaker inhabitants from being drawn in. Pawfly makes the foam in black and lists it for freshwater and marine aquariums.\u003c\/p\u003e\u003ch2\u003eFitting the sponge on a filter intake\u003c\/h2\u003e\u003cp\u003eA 0.83\" diameter opening accepts the intake, and the sponge is pressed onto the fish tank filter's water inlet. Directions from the manufacturer call for swapping the pre-filter sponge for a new one rather than cleaning and reusing it.\u003c\/p\u003e\u003ch2\u003eChecks before you buy\u003c\/h2\u003e\u003cp\u003eMeasure the intake tube on your filter first: the sponge fits a tube that matches its 0.83\" opening, and the 2\" width sets how far it sits out from the inlet. The sponge is listed for freshwater and marine aquariums, so a tank outside those two types is not covered. Its body runs 3.4\" long, which is the space it needs around the intake.\u003c\/p\u003e\u003ch2\u003eFoam body and how it sits in the water\u003c\/h2\u003e\u003cp\u003eThe foam is soft and has high elasticity, so the sponge grips the inlet it is pushed onto. Its inner structure is described as fluffy, and water continues to pass through it at its normal flow.\u003c\/p\u003e\u003cp\u003eThe sponge catches debris, leftover food, waste and plant matter before they reach the filter, and it also keeps that material out of the filter itself. The same layer of foam stands between small tank inhabitants and the intake, so they are not pulled inside.\u003c\/p\u003e\u003ch2\u003eWhat is in the pack\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTwelve pre-filter sponges, model Pawfly-2185-BK\u003c\/li\u003e\n\u003cli\u003eBlack foam, each with a single hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon questions about the pre-filter sponge\u003c\/h2\u003e\u003ch3\u003eHow many sponges come in the pack?\u003c\/h3\u003e\u003cp\u003eThe pack holds 12 sponges, so one order covers twelve intakes or gives spares for later replacements.\u003c\/p\u003e\u003ch3\u003eWhat size hole does the sponge have?\u003c\/h3\u003e\u003cp\u003eThe hole through the sponge measures 0.83\" across, and the single-hole design is made to sit over a filter intake of that size.\u003c\/p\u003e\u003ch3\u003eHow big is each sponge?\u003c\/h3\u003e\u003cp\u003eEach sponge is 3.4\" long and 2\" deep, with the hole running through it for the water inlet.\u003c\/p\u003e\u003ch3\u003eCan it go in a saltwater tank?\u003c\/h3\u003e\u003cp\u003eThe manufacturer lists the sponge for freshwater and marine aquariums.\u003c\/p\u003e\u003ch3\u003eDoes the sponge block the filter's water flow?\u003c\/h3\u003e\u003cp\u003eThe inner structure of the foam is fluffy, and water keeps moving through it at the usual rate.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003ePawfly-2185-BK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColour\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget audience\u003c\/th\u003e\n\u003ctd\u003eFish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUnit count\u003c\/th\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIncluded components\u003c\/th\u003e\n\u003ctd\u003e12 Pack Pre-Filter Sponge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecific uses\u003c\/th\u003e\n\u003ctd\u003eIndoor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Pawfly","offers":[{"title":"Default Title","offer_id":44478976884799,"sku":null,"price":27.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2409\/1199\/files\/pawfly-filter-media-12-pack.jpg?v=1794752811","url":"https:\/\/dogjointly.com\/products\/pawfly-pre-filter-sponge-12-pack","provider":"DogJointly","version":"1.0","type":"link"}
