EHEIM reeflexUV UV-C clarifier im Test: Today we want to look at some models of the Eheim UV-C clarifier series take a closer look. Eheim has three premium models when it comes to one UV clarifier to use. When it makes sense and what distinguishes these products, we will introduce you here. You will also find out what the customers say about it in the tests and we will also make a purchase recommendation. There are three models with different performance data to choose from.
What is the point of a UV-C clarifier in the aquarium
Before we look at the three models mentioned above in detail, we would like to take a quick look at how a UV-C clarifier works. Basically, these devices are all about the germs, be it suspended solids as well as algae spores to reduce in the aquarium. The UV-C clarifiers are normally used in addition to the Aquarium filters deployed. There are different sizes depending on the flow rate and the size of the aquarium. The UV-C clarifier works with UV-C radiation which can not only eliminate algae spores, but also other harmful germs and infectious swarmers from fish parasites. These devices are not only used in breeding tanks.
Eheim reeflexUV350
Let's start with the smallest device in the range. The Eheim reeflexUV350 can already be used in aquariums from 80 liters. Eheim has a particularly good efficiency, mainly due to the built-in reflectors. Compared to other models, where the water is very often diverted in order to gain more surface area, this should run directly through the clarifier in the models of the Eheim reeflexUV series and thus be up to 1,8 times more effective than the competition. The customers are of the same opinion, because here there are full stars in almost all points.
The smallest device in the series, the 350, has a maximum flow performance of 200 liters per hour. If you want to take action against algae and not against harmful germs, you can increase the flow rate even further. Values of up to 400 liters per hour are then possible here. In this way, the turbidity in the aquarium water is quickly eliminated. A quick and effective remedy, especially for floating algae.
The integrated reflector is also made of high-gloss aluminum and therefore reflects the UV-C light particularly well. This process can also reduce energy consumption. The power loss is reduced without a special redirection. The use of an Eheim reeflexUV350 is particularly useful in breeding tanks. Of course, only the floating bacteria are reduced and not the necessary ones Nitrobacter im Filter. The bracket for installation and, of course, detailed operating instructions and assembly instructions are also included with the models.
The Eheim reeflexUV350 can be used from 80 to 350 liters and it only consumes 7 watts of power. Of course, this must be factored into the maintenance costs.

Eheim reeflexUV500
The basic features are in the comparison. the same for the 350 model. But there are big differences here in terms of throughput, because you can already run up to 400 liters per hour to reduce germs and up to 800 liters per hour to combat algae. The aquarium size also ranges from 300 liters to 500 liters. The UV-C clarifier can even be used for smaller breeding systems. When it comes to power consumption, Eheim specifies 500 watts for the Eheim reeflexUV9. This consumption is also impressive in comparison to other models.
- Quickly and effectively reduces the germs present in the water and the parasites dangerous to the fish
- Eliminates the brown haze caused by algae or bacteria
- Attention: UV light. Risk of skin lesions and eyepieces. Never look directly into the light.
- Inside made of shiny aluminum, the UV light is reflected and disinfection is particularly effective
- Excellent results with low energy consumption (1,8 times more effective than standard UV clarificateurs)
Eheim reeflexUV800
The largest model in the series is the Eheim reeflexUV800. Aquariums up to 800 liters are clarified here. You can also get the algae under control here and work with a flow rate of 1200 liters per hour. When sterilizing, this must be halved. The power consumption is just 11 watts at this power. Here, too, we really liked the design and shape. A very good housing with the possibility to change the lamp. As always, Eheim is also a pioneer when it comes to spare parts.

Conclusion and price of the Eheim reeflexUV350 / 500 and 800 UV-C clarifiers
If you look at all the tests that have been published so far, then there is little to remember. If so, it could possibly be the price, because there are some cheaper providers on the net. But also with certain compromises in terms of effectiveness and design. It starts with the Eheim reeflexUV350 model at around 80 euros. The Eheim reeflexUV500 model costs around 95 euros and the large Eheim reeflexUV800 device currently costs around 120 euros. However, the durability is particularly good.
Many customers are totally enthusiastic, especially how clear and clean the aquarium water is after use.
Of course there are also negative reports, even if they are not small. Defective devices are sometimes criticized here, but this can happen with any manufacturer. In addition, the effectiveness against algae is also criticized. Assessing this also requires some knowledge, because a UV-C clarifier cannot be used against every type of algae. There are crucial differences here. Be it in terms of the type of algae, but also simply what patience you should have. Even a UV-C clarifier is not a miracle cure for algae.
In addition, we always recommend that you first take care of the causes, because this is the only way to get rid of algae permanently.
