Recipes for nutrient reduction

The AquaCalculator supports numerous recipes for reducing nutrients

Aktiv-BAK food for filter bacteria

For purely biological degradation of nitrate and phosphate. Serves as food for the naturally occurring filter bacteria. Activates strong growth of biomass.

Reduces NO3/PO4 in a balanced ratio. Measure NO3/PO4 1x/week and adjust the dosage accordingly Target: NO3/PO4 stable at ~0,25 /~0,02 [mg/l]

DIY NO3:PO4-X #3 (Fish and Soft Coral aquariums)

Reduces NO3/PO4 in a balanced ratio. Measure No3 1x/week and adjust the dosage accordingly Target: No3 stable at ~2,5 [mg/l]

DIY NO3:PO4-X #3 (Mixed reef incl. SPS)

Reduces NO3/PO4 in a balanced ratio. Measure NO3/PO4 1x/week and adjust the dosage accordingly Target: NO3/PO4 stable at ~0,25 /~0,02 [mg/l]

EZ DSR: Instant dosing solution for nutrient control

Reduces NO3 and PO4. Serves as food for healthy bacteria cultures. Start dosage. Can still be increased.

Fauna Marin: BACTO Energy

Carbon source for an optimal supply of bacteria that break down pollutants. This binds or breaks down NO2/NO3/PO4. Suitable for aquariums with/without zeolite filtering. Reduce dosage when using phosphate adsorber at the same time.

Fauna Marin: UltraBak

Causes strong proliferation of denitrifying filter bacteria This results in reduction NO2/NO3/PO4 Suitable for aquariums with /without zeolite filtering Reduce dosing if you also use a phosphate adsorber

RedSea: NO3:PO4-X (Enhanced coloration LPS/SPS)

Reduces NO3/PO4 in a balanced ratio. Measure No3/Po4 1x/week and adjust the dosage accordingly Target: NO3>=0,25[mg/l] PO4>=0,02[mg/l]

RedSea: NO3:PO4-X (Fish and soft coral aquariums)

Reduces NO3/PO4 in a balanced ratio. Measure NO3 1x/week and adjust the dosage accordingly Target: NO3 stable at 2,5[mg/l]

Tropic Marin - Elimini Phos

Carbon source for an optimal supply of bacteria that break down pollutants. This binds or breaks down NO2/NO3/PO4. Suitable for aquariums with/without zeolite filtering. Reduce dosage when using phosphate adsorber at the same time.

Vinegar dosing

Reduces especially NO3, but also PO4 From the 15th day the required dosing quantity should have established. Usually this reduces to about 50% of the amount of day 8..14

Vodka Method

Reduces especially NO3, but also PO4 From the 15th day the required dosing quantity should have established. Usually this reduces to about 50% of the amount of day 8..14

Perfect Reefer Tool.

The people or individual who made this application must not only be a fellow reefer but a great designer and innovator. The app is packed with useful knowledge, conversions and methods to reach and maintain targeted goals. This app will help me save time, maintains my tank and make changes with confidence. This application is well worth the money. Thank you. I hope my great words encourage you to continue to update and create more useful tools and applications for the reefing community

FAQ

Frequently asked questions about the AquaCalculator

why subscription?

Software is never finished. To finance further development and support, software is traditionally developed in versions. New versions are released at regular intervals, offering new functions and improvements. In order to enjoy the features of a new version, it had to be bought and paid for again.

This classic version model does not exist with AquaCalculator. We constantly integrate new features and provide updates and improvements. To finance the continuous improvements, the support and our powerful backend aCloud, we have decided on a subscription model.

For a very reasonable annual fee you can use the AquaCalculator universe. Of course, you can cancel at any time if you no longer need the services of AquaCalculator.

How many devices can I use with my subscription?

You can use as many devices as you like within one operating system with your licence. Apple requires that they run under the same Apple ID.

What is it about the different versions for iOS?

There are two different versions of the AquaCalculator for iOS.

The “AquaCalculator Classic” has not been further developed since the end of 2018. However, it is still available for buyers of this version and can still be used.

The current version for macOS is the “AquaCalculator”.

If you are still using the “AquaCalculator Classic” (version 3.8.91), we strongly recommend switching to the current version, which can be found as “AquaCalculator” in the AppStore.

What is it about the different versions for macOS?

AquaCalculator for macOS is currently available in two versions.

The AquaCalculator CL (CL = Classic) is the version of the AquaCalculator developed specifically for macOS. It is the solution for all those who still use macOS before the Monterey version. It requires its own licence which cannot be used for iOS / iPadOS. It will continue to receive updates regarding balling recipes, salts and other data, but will no longer be technically developed.

The “AquaCalculator” without CL is the current macOS version. It is developed together with the iOS / iPad version. It runs from macOS BigSur. If your operating system is older, you have to use the “AquaCalculator CL”.

With the “AquaCalculator” for macOS there is a licence for all Apple systems. It is valid for the macOS, iOS and iPadOS versions.

If you use the “AquaCalculator CL”, you should change to the “AquaCalculator”.

Can I use my iOS subscription for macOS, Windows or Android or vice versa?

No. They are each independently developed products, each of which requires its own licence at the moment.

Is there a subscription that allows me to use all versions?

We do not offer so-called cross-licensing models of AquaCalculator. This has several reasons:

  • Contract conditions of the AppStores make such models uninteresting or even impossible. Remember: Apple, Microsoft, Google & Co. want to earn money from the purchases. Cross-licences are therefore a thorn in their side.
  • Large programming effort in the applications and on the server side.
  • We work with 3 programmers on 4 different versions. Fair distribution of income complicated. You pay fair prices and only for the version you use.
  • Fair for you, fair for us…

can I use the code for the Windows version that comes with my Fauna Marin package for iOS, Android or maOS?

No. The use included with Fauna Marin currently only refers to the Windows version. For technical reasons, the licence can unfortunately only be used for the Windows version, as the store systems required on the other platforms Android, iOS and macOS (App Store, Google Play Store) do not provide for “vouchers”.

how can I view, change or cancel subscriptions?

  • iOS You can find detailed information on canceling your subscription here:
