Review: A little over priced for what it is IMO - Ok. So I have refused to buy one for nearly ten years since having a reef aquarium. I’ve made DIY auto top up units over the years for a few quid and had no issues. This time though I have a new massive system and spent absolute fortunes, so figured being tight on this, one of the most important things really wouldn’t be smart. The unit is great. Easy to set up and comes with some safety features to prevent over filling, alerts you when the RO reservoir is empty and maintains the salinity perfectly. The only downside I’ve encountered is the pump is noisy once activated. A small annoyance for me as the aquarium is in my living room. Let’s face it the price is way over the top for what it actually is. Tunze think they are the Gucci of aquatics in my experience so what can you do...
Review: Simple effective and sensitive. - Initially put off buying as I could’ve find any info about how far the float has to drop before triggering the pump. I’m happy to report that it’s only needs to drop about 2mm, making it ideal for small aquariums. Easy to put together, set up and works perfectly. Has a useful safety timer so can’t overfill the tank if the float gets stuck. Can’t get the pump to sit upright in the bucket because of the kinked tubing and cable.

Such a great device. Completely changed the way I can manage my tank and my holidays :-) It's on test since last three weeks and it's perfect for my 20 liters open tank, the water level fluctuation is really negligible. I'm now going on holidays for three weeks I trust this little toy will do a great job for me!
