know this, that is not a problem. Normally you never power oﬀ the Alkatronic, and if

you do, just press ‘extra measurement” upon restarting to do a fresh measurement

so the third part computer will have a fresh value to read. After that, Alkatronic will

continuously send the last measured value to the aquariumcomputer. "

We can not take any responsibility for whether or not the aquariumcomputer

interprets the value as correct, we can only control our signal from Alkatronic

and guarantee that is correct. "

Programming tip to Apex/aquariumcomputer-user

As the signal to Apex/Proﬁlux/other ”third party aquarium-computer”=(TAQ), is

analogue, it will ﬂuctuate some 1/100ths up and down. This is the case for all

analogue signals, like temp, pH, ORP etc. In the TAQ you will probably want to set

reference levels when you want diﬀerent things to happen if your value is below, or

above a certain level. Remember to always use the command ”Defer”, to

prevent bouncing between on and oﬀ if the values are very near your settled

reference value. "

Ex:(

In your Apex you want to shut oﬀ the CO

-solenoid if dKH is above 8.50 dKH. If

Alkatronic measures for instance 8.45 dKH, the value in your Apex from time to time

could go above 8.50 due to the small instability of the analogue signal. You do not

want your Apex to react to these minor and temporary ﬂuctuations above your

reference values. You need to add a function in your Apex code that tells your apex

to only react if the value have been outside your reference values for a certain

amount of time. In Apex you call this Defer. "

In the example below, you want Apex to shut oﬀ an outlet if dKH is above 8.50 dKH,

but only if it is above that level for more than 10 minutes. This will prevent the

Apex from bouncing between on and oﬀ, if you are very close to the settled

reference level.

Fallback ON"

Set ON"

If dKH > 8.50 Then OFF "

Defer 010:00 Then OFF"

Cloud-functions

With the cloud, you can reach the measuring data, export all data to an excel-ﬁle,

and control some of the functions, from a place outside the home. Do not forget to

have the button ”Upload mode” in enabled position. Open this link in a web-
