It keeps your Nexus 220 or 320 filter (2006 models onwards) cleaning itself to a consistent schedule, connecting straight into your existing pond pump and mains supply.\u003c\/p\u003e\u003ch2 class=\"h4\"\u003eOverview\u003c\/h2\u003e\u003cp\u003eThe Nexus Automatic Pump Fed System is an add-on control kit that automates the cleaning cycle on compatible Nexus filters, replacing manual ball-valve turning and pump switching with a timer-driven or push-button cycle. It fits Nexus 220 and 320 filters manufactured from 2006 onwards that run on a pump-fed setup, wiring into your existing pond pump and mains power rather than needing new equipment. That keeps the maintenance routine consistent even when you're not there to do it by hand.\u003c\/p\u003e\u003ch2 class=\"h4\"\u003eHow the cleaning cycle works\u003c\/h2\u003e\u003cp\u003eOnce wired in, the control unit handles every step of the cycle in sequence: the timer, or the manual clean button, starts things off, the circulating pump switches off, the water level inside the Nexus equalises, air is diverted from the bio-chamber to clean the media in the Eazy, the automated waste valve opens to drain it to waste, closes again, air returns to the bio-chamber, and the circulating pump switches back on as the filter returns to normal filtration. You don't need to be present for any of it, and you can still force a clean cycle on demand.\u003c\/p\u003e\u003cp\u003e### What's in the kit This control box connects to an automated waste valve and an airpump control box, which between them carry out the draining and air-diversion steps described above. Evolution Aqua's wider Automatic System range also includes an inlet slide plate for gravity-fed installations, but that's a gravity-fed component and isn't part of how this version operates.\u003c\/p\u003e\u003cp\u003e### Setting the cycle timer There's no single fixed schedule, since ideal timing depends on your pond. The general rule of thumb for ornamental fish keeping is to exchange around 10% of your total water volume weekly, so it's worth setting your cycle frequency with that in mind. Filter turnover, how long it takes your whole pond volume to pass through the filter once, is best kept to roughly every 2 to 3 hours, which is a useful reference point when deciding how often to run cleans.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible filters\u003c\/td\u003e\n\u003ctd\u003eNexus 220 and 320 filters manufactured after 2006\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation type\u003c\/td\u003e\n\u003ctd\u003ePump-fed Nexus installations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit contents\u003c\/td\u003e\n\u003ctd\u003eControl box, connection to automated waste valve, airpump control box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCleaning cycle activation\u003c\/td\u003e\n\u003ctd\u003eAdjustable timer or manual clean button\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower connection\u003c\/td\u003e\n\u003ctd\u003eMains power\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AquaticsHub","offers":[{"title":"Default","offer_id":57611502190965,"sku":null,"price":579.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/0610\/4949\/files\/EA_Nexus_Automatic.png?v=1790459971","url":"https:\/\/aquaticshub.co.uk\/products\/evolution-aqua-nexus-automatic-pump-fed-system","provider":"AquaticsHub","version":"1.0","type":"link"}
