The reference software for dedicated marine aquarists
The AquaCalculator is not free. In order to be able to use the AquaCalculator permanently, you must complete a paid subscription after two weeks. In the first two weeks, the AquaCalculator can be tested for free and the subscription can be stopped at any time before it is chargeable.
The app for documentation and management of your aquarium. The main focus is on saltwater aquariums but also their freshwater pools can of course be documented with the AquaCalculator.
With the AquaCalculator you have the suitable manager at your fingertips to keep an eye on all important parameters regarding the care of your aquarium.
A big request: unfortunately we can not respond to reviews. If you have problems with the app, please contact us via email shortly (Support). So far we could clarify every question :-)
The reference software for every dedicated marine aquarist:
- Manage several basins in parallel
- Documentation of the water values in graph and table form per pool. You can document your water readings, take notes or deposit pictures. The pictures can also be commented on.
- Animal Administration. You can also assign notes and pictures to your animals in the basin and thus get a quicker overview of the development of their stock.
- Dates: Management of recurrent memories help to keep track of the care of aquariums
- Realistic estimation of the required salt quantity of commercially available sea salt mixtures.
How much salt is actually needed to "adjust the salt content" or for the next "water change"? AquaCalculator calculates this using self-determined measurements of almost all commercially available sea salt mixtures.
- Addition of nutrients (nitrate and phosphate)
- Calculator to adjust calcium / alkalinity / magnesium: Expensive special agents are passé. AquaCalculator calculates the exact dosing quantities and stock solutions required for the adjustment of calcium, alkalinity (KH) and Mg concentration of low-cost salts.
Supports recipes from Aquafair, Aquaforest, Coral-Care, Fauna Marin, MT Aquaristics, Nyos, H.W. Balling, Price Aquaristics, A.Glaser, Red Sea, Sangokai, Tropic Marin, Fritz ProAquatics, Two Little Fishies, Kent Marine, Seachem, Brightwell, Continuum Aquatics, ESV and Self-Defined.
- Extensive setting options for the measuring instruments used, as well as the chem. Recipes.
- Mini-FAQ: answers the most important questions about adjusting the water values and thus the successful care of reef aquariums. Including ten thousand times downloaded seawater FAQs by Martin Kuhn (Water Parameter FAQ, Anemone FAQ, Plague Master FAQs 1 and 2)
NOTE: We have provided iBooks from Apple for viewing the Seawater FAQs. The ad must have iBooks or another PDF viewing app installed on your device.
