Running it dry will damage the impeller\u003c\/li\u003e\n\u003cli\u003eLeave a little clearance behind the tank for the body of the filter\u003c\/li\u003e\n\u003cli\u003eA new tank has no bacteria in it. Cycling — running the filter for several weeks until it processes ammonia and nitrite to zero — has to happen before fish go in, or they sit in their own waste while the bacteria catch up\u003c\/li\u003e\n\u003cli\u003eNo filter is silent. Most of the noise people complain about is air trapped in the impeller housing or a unit that is not sitting level\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNever wash biological media in tap water and never replace it all at once. Chlorine kills the bacteria living on it, and changing everything together restarts the cycle\u003c\/li\u003e\n\u003cli\u003eRinse mechanical foam in a bucket of old tank water rather than under the tap\u003c\/li\u003e\n\u003cli\u003eChange the carbon monthly. Carbon becomes exhausted rather than dirty, and spent carbon does nothing\u003c\/li\u003e\n\u003cli\u003eReplace only part of the BIOMAX at a time, so the bacterial population survives\u003c\/li\u003e\n\u003cli\u003eUnplug anything electrical before putting your hands in the tank\u003c\/li\u003e\n\u003cli\u003eA liquid test kit for ammonia, nitrite and nitrate tells you more about a tank than anything you can see\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eGood To Know\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSuperseded by the Fluval AC20, which Fluval lists as the direct replacement for this model\u003c\/li\u003e\n\u003cli\u003eHang-on filters need the water level kept up. Let it drop and the return splashes, which is noisy and gases off CO2 in a planted tank\u003c\/li\u003e\n\u003cli\u003eThe outflow is a waterfall. That suits most community tanks but is too much current for a betta or a long-finned fancy goldfish\u003c\/li\u003e\n\u003cli\u003eMost tanks want 20–30% of the water changed weekly, with the replacement dechlorinated and matched for temperature\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fluval","offers":[{"title":"Default Title","offer_id":44380553281787,"sku":"HAA595","price":130.0,"currency_code":"AED","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/8211\/8139\/products\/fluval-fluval-aquaclear-20-power-filter-5-20-us-gal-18-76-l-977721.jpg?v=1747246424","url":"https:\/\/www.thepetsclub.ae\/products\/fluval-aquaclear-20-power-filter","provider":"The Pets Club","version":"1.0","type":"link"}
