BRS Titanium heater causing Ph probe interference

[Frank Li]

Are you saying there is only one ground probe required as opposed to two (one going to outlet and one going to the controller) which is what I gathered from earlier on this thread?

You only need one ground probe, but you "should" have 2 connections to it.
- One connection to the earth on your AC mains for safety, this ensures any stray AC current in your aquarium water has a low resistance path to ground to protect yourself and if it gets high enough, to trip the saftey switch.
- The other connection to a ground is to your controller. This connection is to ensure the ground reference of the water is the same for the ph probe being added to it as your aquarium water is not isolated. It is normally easier you use 2 ground probes instead of trying to daisy chain multiple connections to a single probe, but each to their own how you wish to spaghettify your reef.

Simply put, you need to run two ground wires into the aquarium because they solve completely different problems. The first wire protects you from an electric shock if a pump short-circuits into the water and trips the circuit breaker. The second wire is needed solely for the controller’s circuitry to eliminate electrical noise and prevent the pH meter from showing the weather on Mars. Frank Li is absolutely right: instead of clumsily twisting two wires onto a single grounding pin and risking burning out the delicate electronics, it’s much easier and safer to buy two separate grounding wires and sleep soundly.

So you are a bot, that is sad.

@Carlos can you remove the bot from your services please, we don't need the echo.
