Thinking about buying a density probe to setup an auto water changing system using a fresh water reservoirand a high density reservoir. I have heard reports that the density probes are not too reliable - is this still  the case? can anyone sugest any config for the required program to add water water from either reservoir based on the density? do I need to add any delays? Thanks in advance

Hi aqalityplace,

i think that it's not a good solution to use a density probe for the ater changing, the probe can be slow in it's changes....

In a feature FW revsion (8.0) there will be the possibilty to execute sequential programs, so you will be able to make a program with 2 level sensors to make the water changes.

Bye
