Software which may make your life a bit easier

by John and George J. Reclos

We feel that we should start this page by declaring that we have nothing to do with programming, writing code or anything alike. We have just found some ways to save time and we would simply like to share this with you. The software you see in this page is "elementary" and we are sure that if some skillful hobbyist spends some time on them they will look much better - even become more functional. If some of you feel you could give us a hand and present them in a much better way, please do so, we will be happy to present your version here. It goes without saying that everybody is allowed to download and distribute those simple pieces of software.

Determining the CO2 content of your water when you know the pH and the KH. Just insert the pH and KH numbers in the corresponding cells (you will see red zeros when you first start the program) and get the CO2 content in ppm in B4 (in blue). A snapshot of the program is shown below. Requires Microsoft Excel.

Determining the drop of temperature during a water change with cold water. You need to insert the volume of the water in your tank (cell B3), the temperature of the water in your tank (cell B4), the percentage of water you wish to change (cell B5) and finally the temperature of the cold water (cell B6). The final water temperature will appear in cell C7. You can see the relevant article here. If the final water temperature appears to be too low, decrease the percentage of the water to be changed until you get an acceptable value in C7. A snapshot of the program is shown below. Requires Microsoft Excel.

Calculating the appropriate tank size for your fish (as described in this article). Software developed by John G. Reclos in Turbo Pascal. Snapshots of the program are shown below. The program executes in an MS-DOS window by itself. If you want to run the program again you must close the window and restart it. The shots below show the data input stages and the final screen with the recommended dimensions and volume of the tank. Please note that the program will give you the "ideal" dimensions for the kind of fish you want to keep. It is entirely possible to get tanks of the same volume with completely different tank dimensions depending on the fish you want to keep. This program is a "help" tool to avoid using the formulas shown in the article. However, we strongly recommend reading the article and use "manual" override and common sense. Usually the fish can be kept in smaller quarters but here you will get a first idea of the kind of tank you should look for. This formula applies for fish which have a final adult size of 20 cm.

Converting temperature for your fish (as described in this article). Software developed by John G. Reclos in Turbo Pascal. Snapshots of the program are shown below. The program executes in an MS-DOS window by itself. If you want to run the program again you must close the window (by pressing [enter]) and restart it. The shots below show the data input stages and the final screen with the temperature expressed in Celsius, Fahrenheit and Kelvin degrees.

Tienie de Coning, from Jeffreys Bay, in South Africa sent us the following program which is used to keep track of all changes and parameters in an aquarium system. The program can be easily modified to suit everybody's specific needs. The two pictures below show the "health" page as well as the different sheets which are already prepared.
