About this app

The AquaCalculator is not free. This application requires a valid subscription. Without a valid subscription, you can only read your data but not change it.

The app for documenting and managing your aquarium. The main focus is on seawater aquariums, but your freshwater tank can of course also be documented with the AquaCalculator.

With the AquaCalculator you have the right manager at hand to keep an eye on all the important parameters related to the care of your pool.

The reference software for every committed saltwater aquarist:

• Manage multiple aquariums in parallel

• Documentation of the water values in graphic and tabular form for each pool. You can document your water values, take notes or store pictures. Comments can also be added to the images.

• Animal management. You can also assign notes and images to your animals in the tank and thus get a quicker overview of the development of your population. Divide into fish, invertebrates, coral or anemone.

• Realistic estimate of the amount of salt required for 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 measured values of almost all sea salt mixtures available on the market.

• Addition and reduction of nutrients (nitrate and phosphate)

• Calculator for adjusting calcium / alkalinity / magnesium: Expensive special products are a thing of the past. AquaCalculator calculates the required dosing quantities and stock solutions to adjust the calcium, alkalinity (KH) and Mg concentration of inexpensive salts with mol accuracy.
More than 120 recipes are supported by Aquafair, Aquaforest, Coral-Care, Fauna Marin, MT-Aquaristik, Nyos, H.W. Balling, Preis Aquaristik, 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 devices used, as well as the chemical recipes used by the program.

• Mini-FAQ: Answers the most important questions about setting the water values and thus about the successful maintenance of reef aquariums. Including the seawater FAQs by Martin Kuhn that have been downloaded tens of thousands of times (water parameter FAQ, anemone FAQ, pest FAQ 1 and 2)
