Seems great so far

I’ve only been using it for a couple of days but so far I really like it. The only thing I haven’t figured out is how to do recurring reminders. Is that possible? If not, the reminders are less useful. Could totally be user error here.

I love this app

Best salt Water app ever 👍🏾

A little disappointed.

I got this app to help my 11 year old son track out new tank. I especially got it for the reminders that are shown to be able to add. Well I can’t add reminders, and there is little to nothing more than I can get from a free app.

Developer Response ,

Please email us at for details on how you are unable to add reminders or if there is a specific thing you are trying to do. We are always taking suggestions and changing the app to our users needs. Reminders are added in three ways: Through the system menu for the aquarium, in each individual parameter and in the bottom tab as of version 2.4.5
