Bacteria get far more oxygen there than they do submerged, which is why a trickle stage punches above its size\u003c\/li\u003e\n\u003cli\u003eRe-filtration chamber lengthens the time water spends in contact with the media\u003c\/li\u003e\n\u003cli\u003eTwo sizes, C2 and C4, for progressively larger tanks\u003c\/li\u003e\n\u003cli\u003eMedia stages are reachable from the top without dismantling the unit\u003c\/li\u003e\n\u003cli\u003eFor use in both freshwater and saltwater aquariums\u003c\/li\u003e\n\u003cli\u003eMade by Fluval, the aquatics brand of Rolf C.

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\u003eKeep the tank topped up. A dropping water level is what makes a hang-on filter noisy\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\u003eChange one stage at a time so the bacteria survive the clean\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\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\u003eDo not let the trickle chamber dry out — the bacteria in it die within hours if the flow stops\u003c\/li\u003e\n\u003cli\u003eUnplug anything electrical before putting your hands in the tank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eGood To Know\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe trickle stage is the real reason to choose a C-Series over a plain hang-on filter. It gives biological capacity closer to a small canister\u003c\/li\u003e\n\u003cli\u003eIt needs clearance behind the tank, and it is deeper front-to-back than a basic hang-on filter\u003c\/li\u003e\n\u003cli\u003eThe waterfall return is strong. Baffle it or turn it down for bettas and long-finned fish\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":"C2","offer_id":44383282495739,"sku":"HA14001","price":226.0,"currency_code":"AED","in_stock":true},{"title":"C4","offer_id":44383282528507,"sku":"HA14003","price":385.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/8211\/8139\/products\/fluval-fluval-power-filter-c4-723369.jpg?v=1749654556","url":"https:\/\/www.thepetsclub.ae\/products\/fluval-c-series-clip-on-power-filter","provider":"The Pets Club","version":"1.0","type":"link"}
