ATO recommendations....

I have the Fluval 13.5 EVO. I have had the tank for almost a year now. I am looking to add an ATO to it now. Does anyone have any suggestions?

Tunze. They just work. I don't remember the number of the nano version. Tunze nonetheless

Second the tunze nano. Reliable and affordable.

That said i use the IM hydrofil on my tank with no issues.

Bought the tunze nano for my bio cube, works and continues to work. Bought the apex for my larger display. Needed something to pump ato from my basement. Both are worth every penny.

Smart Micro ATO. The only one I'd ever use.
