{"title":"Aquarium Internal Filters","description":"\u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eAquarium filters in general help generate flow, absorb substances that causes turbidity, and enrich the water with oxygen. Beneficial bacteria that settles within the unit’s filter media help to break down and remove waste from aquarium inhabitants. Internal filters are suitable for small aquariums and can be used for paludariums. These filters are placed inside the aquarium, usually in a corner. Internal filters can also be used as a secondary filter, or if there is no space outside the aquarium.  A key advantage is that no visible tubing connections interfere with the aquarium's overall aesthetic.\u003c\/span\u003e","products":[{"product_id":"oase-biocompact-25","title":"BioCompact 25","description":"\u003cul\u003e\n\u003cli\u003eCompact – Designed to be discreetly installed horizontally or vertically, this filter is perfect for small freshwater aquariums and paludariums\u003c\/li\u003e\n\u003cli\u003eLarge filter surface for effective water filtration – Uses biological, mechanical, and chemical filtration for optimal water quality and clarity\u003c\/li\u003e\n\u003cli\u003eCarbon filter foam – Activated carbon absorbs unwanted substances in aquarium water.
