Hi, I am interested in opinions on the Oxygen sensor.

I have a Profilux 3 Starter Kit plus the Redox/Conductivity Expansion Card and Sensors.

I have also been thinking about installing an Oxygen sensor but I am unsure of whether it is worthwhile and whether I can do that in my Profilux 3 which already has the Redox/Conductivity Module.

Can I do this?

Is it worth doing?

I have had some problems with water quality and my fish have been at the top of the tank gulping for air – a some quick water changes and all is OK again but I do not want to stress my fish like that ☹ Of course the solution is nto to have problems but if I do, I want to know quickly.




Thanks
Greg
