The G3 canister was rated for aquariums up to roughly 300 litres (80 US gallons) at up to 700 L\/h (185 US GPH). Fluval has discontinued the G3 unit itself, but this cartridge remains available for the many G3 filters still running.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePleated mechanical media\u003c\/strong\u003e — folds increase surface area so the cartridge traps more debris before it needs rinsing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo-bypass frame\u003c\/strong\u003e — water is forced through the pleats rather than around them, so nothing skips the mechanical stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaily-use rating\u003c\/strong\u003e — designed to be the fastest-clogging, most frequently serviced stage in the G3, ahead of the chemical and biological baskets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFresh and marine safe\u003c\/strong\u003e — inert media with no chemical additives, so it won't affect salinity, pH or medication dosing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eFluval part number\u003c\/th\u003e\n\u003ctd\u003eA415\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eFluval G3 Advanced Filtration System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMedia type\u003c\/th\u003e\n\u003ctd\u003ePleated mechanical filter media, no-bypass frame\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePack quantity\u003c\/th\u003e\n\u003ctd\u003e1 cartridge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater type\u003c\/th\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eWill it fit my filter?\u003c\/h3\u003e\u003cp\u003eThis cartridge is specific to the G3. The larger G6 uses the equivalent A416 cartridge, sold separately as the Fluval Pre Filter Cartridge G6 — the two are not interchangeable, since the G3 and G6 media baskets are different sizes. The model name is moulded into the lid of the canister if you need to check which one you have.\u003c\/p\u003e\u003ch3\u003eWhich G3 pre-filter do I need?\u003c\/h3\u003e\u003cp\u003eFluval sells two pre-filter options for the G3: this standard pleated cartridge (A415), and the Fluval Fine Pre-Filter Cartridge G3 (A417), which uses a denser pad to catch finer particles at the cost of clogging faster. Most tanks run the standard A415 day to day and add the fine version only when water clarity is a specific problem.\u003c\/p\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eRinse in removed aquarium water every 2–3 weeks, or sooner if flow through the G3 visibly drops. The pleats mean it can usually be rinsed and reused several times before it needs replacing — replace once the pleats stay compressed or torn after rinsing.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cp\u003eSuitable for any Fluval G3 running fresh or marine water.

The G3's chemical and biological media are sold as separate cartridges and baskets.\u003c\/p\u003e\u003ch4\u003eCan I use it in a G6?\u003c\/h4\u003e\u003cp\u003eNo. The G6 uses the A416 cartridge, which is a different size to fit the G6's larger media basket.\u003c\/p\u003e\u003ch4\u003eHow do I know if it needs replacing rather than rinsing?\u003c\/h4\u003e\u003cp\u003eIf the pleats stay flattened or the cartridge is torn after a rinse, or flow through the G3 doesn't recover after cleaning, replace it.\u003c\/p\u003e\u003ch4\u003eIs it safe in a marine tank?\u003c\/h4\u003e\u003cp\u003eYes.
