Fluval's Flex 2.0 range uses a different, redesigned media stack from the original (non-2.0) Flex aquariums, so parts are not interchangeable between the two generations. If your tank is the Flex 2.0 34 L instead, you need Fluval's foam block sized for that model, not this one — check your tank's box or rating plate for \"9 US Gal \/ 34 L\" versus \"15 US Gal \/ 57 L\" if you're unsure which you own.\u003c\/p\u003e\n\u003ch4\u003eIs this the same foam as the original Fluval Flex?\u003c\/h4\u003e\n\u003cp\u003eNo. The original Flex 15 Gal\/57 L uses a separate part, Fluval A1375. Fluval does not list A1409 as compatible with that earlier range, so the two are not interchangeable.\u003c\/p\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eRinse the foam in tank water, never tap water, whenever it looks visibly clogged or flow slows noticeably — tap water's chlorine will kill the beneficial bacteria living in the rest of the filter. Fluval recommends a full replacement every 12 months, even with regular rinsing, once the foam has compacted and lost its ability to trap fine debris.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cp\u003eSuitable for any Fluval Flex 2.0 57 L aquarium kit, freshwater or saltwater.
