{"product_id":"ocean-free-hydra-filtron-canister-filter","title":"Ocean Free Hydra Filtron Canister Filter","description":"\u003cp\u003eA four-stage external canister filter for freshwater or marine tanks from 80 L up to 800 L, depending on model. What separates it from a conventional three-stage canister is the fourth stage: a Cata-Pure cartridge sitting between two electro-plates, which Ocean Free calls Hydro-Pure Technology. It generates hydroxyl radicals that break down ammonia and nitrite, shortening the cycling period of a new tank. That extra stage draws a small amount of mains power continuously, so it is not the filter to pick if you want a purely mechanical, unpowered-media setup.\u003c\/p\u003e\n\u003cp\u003eSize by the tank you actually have, not the one you plan to buy — running a 1800 on a 200 L tank creates more flow than most community fish enjoy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltron 1000\u003c\/strong\u003e — 80–300 L tanks, 1,000 L\/h pump (600 L\/h circulation), 4.7 L media in 3 baskets, 13 W, 240 × 240 × 363 mm, 16\/22 mm hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltron 1500\u003c\/strong\u003e — 150–600 L tanks, 1,500 L\/h pump (900 L\/h circulation), 7.0 L media in 3 baskets, 23 W, 272 × 272 × 403 mm, 19\/25 mm hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltron 1800\u003c\/strong\u003e — 200–800 L tanks, 1,800 L\/h pump (1,100 L\/h circulation), 10.0 L media in 4 baskets, 32 W, 300 × 300 × 443 mm, 19\/25 mm hose\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-pull priming\u003c\/strong\u003e — the canister self-fills without siphoning by mouth or bucket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet and outlet valves\u003c\/strong\u003e — the hoses stay full when you disconnect for a media change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in surface skimmer\u003c\/strong\u003e — clears the oil film that blocks gas exchange and light\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCata-Pure cartridge\u003c\/strong\u003e — replaced roughly every 9–12 months depending on stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eReplacement parts\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWool, impeller, o-rings, hose adaptors and canister bodies are stocked for all three models — see the \u003ca href=\"\/collections\/ocean-free\"\u003eOcean Free range\u003c\/a\u003e and \u003ca href=\"\/collections\/fish-filters-and-media\"\u003eFish Filters and Media\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.yihufish.com\/products-2\/filter\/of-hydra-powered-by-hydro-pure-technology\/hydra-filtron\/\" rel=\"nofollow noopener\" target=\"_blank\"\u003eMore about this range at Ocean Free (Yi Hu Fish Farm Trading)\u003c\/a\u003e\u003c\/p\u003e","brand":"Ocean Free","offers":[{"title":"1000","offer_id":56007243891010,"sku":"OCEANFREE021","price":303.75,"currency_code":"AUD","in_stock":false},{"title":"1500","offer_id":56007243923778,"sku":"OCEANFREE022","price":399.92,"currency_code":"AUD","in_stock":true},{"title":"1800","offer_id":56007243956546,"sku":"OCEANFREE023","price":480.07,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6676\/0120\/files\/QHU75.png?v=1787816982","url":"https:\/\/www.peekapaw.com.au\/products\/ocean-free-hydra-filtron-canister-filter","provider":"PeekAPaw Pet Supplies","version":"1.0","type":"link"}
