Controlling salinity with apex

[Cary Meredith]

Ok let's start, I am dosing tropic marin 3 part balling and it was stated might see salinity creep up. So I thought perfect time to get an apex with salinity probe to monitor. Started thinking can I automatically remove salt water if salinity creeps up above a certain level and let ato automatically refill to lower salinity. I believe this is possible with use of the fmm module and pmup utility pump, can someone please comfirm and suggest programming to accomplis this.

Thanks
Cary

I would not trust a salinity probe to take any action. Monitoring might be a better idea and then you can check with a trustworthy instrument before you do anything.

Hobby probes are just horrible, at least compared to other tools in other industries. Even "lab grade" probes fail or drift at too high of a rate.

I couldn’t agree more with above. I like that my apex has the salinity probe but there is no chance I would trust it enough to adjust my salinity.

Although my second apex probe seems to be very good i still would not trust it at all to control off of. Just see how much it changes by week to week and then make your water change slightly lower salinity. I cant imagine its going to skyrockey.
