Hello Everyone!

I have a 13.5 gallon reef fluval Evo tank, i was looking for a decent but not crazy expensive auto top off system, ive done some research but I couldn't find anything good. I was wondering if anyone has had experience with one or know a system which is good and decent?

Tunze Osmolator is the best ATO I've ever used and they do make a Nano version.

My AutoAqua ATO is awesome! I have the cheaper one that doesn’t have an alarm. Keeps the water level super precise. My other favorite is the Tsunami ATO by Eheim. Uses a simple barometric tube sensor thingy and is super reliable. Only reason I didn’t use it on my current tank is because it would fit properly

I use the AutoAqua Micro ATO on a few of my tanks but I think that it has been discontinued. You have me curious to look at the Tsunami!

I love the tsunami! The tech is super simple and knock on wood I have never seen one fail. I also like it better than the optical sensor ones because you don’t have to keep moving the sensor around after water changes
