Hi there,
What is iks?
For my top off, I have a
float switch in the fuge, connected to a PH in my ro/di tank. When the float switch is activated, turns on the PH which sends water to the DIY
kalk reactor and into the sump. There is a timer on the kalk reactor for the PH which recirculates it and keeps the water saturated.
What you are looking for is an Aquarium Controller, aside from a "real" controller I don't know of any software for this purpose. Here is a link that I have been following and once it's finished will be making one. Sure beats the $600 to 900 for one of those Octopus'.

Maybe someone else will know.
