For this video, I wanted to show you one of the products that I came across recently. An auto top off device is an necessity for most reefers, and the majority of you guys will agree that good ones are worth their weight in gold.

XP Aqua, a reputable company that I have known about for few years now and have been covering them since an Interzoo many years ago, where they announced their first Duetto as well as many products for their line up.

Being the smallest form factor, this works for so many different applications and made me truly appreciate it’s versatility over the years in different projects that I was involved in.

Apparently I am not the only one, as many companies has been working with them to have XP Aqua to make their version of an ATO for their respective brands. I am excited to share the new version with you guys and show you the main difference between the first version and the second version and give you another solid option so that you can make an informed decision on your purchases.

Hope you guys like it and let me know what you think down below.

Happy reefing!
