Review: Ignore the negative reviews about water temperature - I liked the unique idea of taking the heater out of the.tank as soon as I saw it. It was also an established brand and was a size which could neatly fit behind my tank. However I was put off by the reviews which said it was difficult to achieve 25 degrees in the tank water. However after viewing many other filters, I discovered a video from an aquarist company which explained the problem of temperature. Basically many people use a thermometer stuck to the outside of the glass which measure the glass temperature not the water. I bought an internal thermometer and the filter and temperature was spot on. Bonus is the filter is very easy to set up. Just stand it in a container for spilt water when you clean it. My tank will now be cleaned more frequently and is much tidier. Oase you just need to include a uv light now Review: Excellent filter for a small tank - Really delighted with this filter for one of my small (50 litre) tanks. Sett up is reasonably straightforward. It doesn't self prime from initial set up or after maintenance so the easiest way to do it is to remove the end of the inlet hose from the filter, suck until it starts to syphon, and quickly reattach. You can either have the heater in the filter or, if you'd rather have more media, use it separately. Once running and free of air, the filter is whisper quiet. Overall, it's excellent. ## Features - INTEGRATED HEATER: Fitted with a HeatUp 100 adjustable control heater, this fish tank filter gives you precise control over water temperature without taking space inside the tank. - MULTI-STAGE FILTRATION: Delivering a generous 1.3 L plus, 0.7 L pre-filter volume in a compact unit, this filter captures debris efficiently and promotes healthy bacteria growth. - EASY ACCESS: The unique EasyClick mechanism provides effortless access to the filter, while its automatic shut-off prevents water flow during cleaning to prevent leaks. - ADJUSTABLE WATER FLOW: The Thermo's inlet and outlet adapters allow complete control of the water flow rate, reaching up to 600 litres per hour with an efficient 11 watt pump. - COMPLETE SET: This complete aquarium filter set comes with filter media, adapters, hoses, and intake/outlet pipes, diffuser, and self-venting system, so you can start filtering immediately. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HZYWCUO | | Best Sellers Rank | 10,635 in Pet Supplies ( See Top 100 in Pet Supplies ) 40 in Aquarium Filters | | Brand | Oase | | Brand Name | Oase | | Customer Reviews | 3.9 out of 5 stars 175 Reviews | | Included Components | Filter, Heater | | Item Form | Filter, Granules | | Item Type Name | Aquarium, Filter | | Item Weight | 2.32 Kilograms | | Item form | Filter, Granules | | Item weight | 2.32 Kilograms | | Liquid Volume | 1 Millilitres | | Liquid volume | 1 Millilitres | | Manufacturer | OASE GmbH | | Manufacturer Part Number | 42684 | | Model Number | 42684 | | Number of Items | 1 | | Pet Type | Fish | | Product Warranty | 3 year manufacturer | | Target Species | Fish | | Unit Count | 1.0 count | | Unit count | 1.0 count | ## Product Details - **Brand:** Oase - **Item form:** Filter, Granules - **Item weight:** 2.32 Kilograms - **Liquid volume:** 1 Millilitres - **Unit count:** 1.0 count ## Images ![Oase FiltoSmart Thermo 100 Aquarium Filter, External Aquarium Filter for Freshwater and Marine Aquariums up to 100 L, including Heater HeatUp 100 W - Image 1](https://m.media-amazon.com/images/I/51lzvIIfzoL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ignore the negative reviews about water temperature *by B***N on 14 September 2026* I liked the unique idea of taking the heater out of the.tank as soon as I saw it.
