It's a shame it doesn't connect to the acloud

The best parameter tracking app I've found for Android! Would love to see some more American supplements like B Ionic added. Although the salt list is already extensive! Also would like the option for making salinity adjustments based on the salinity of the new water being mixed as opposed to the weight of the salt to be added. I don't have a scale that accurate.

This software is well known among reefers, and finally it comes to Android. Given the usefulness of this tool it is well worth buying. Since v1.3 compatibility for Honeycomb devices has been greatly improved. Five stars.

Good program, could be awesome (5star) if the app was updated. Some things are still not translated to English, everyone with a REEF aquarium should know anyway.
