pH range question for those who have a controller

Hey Greg, I have been battling the thought of a controller. Do you like yours?

If so, can you use them with a dosing pump. I am looking at automating the vodka dosing, MG, St, Ca and ALK.

Hey Rick, so far I love it

I still want to get a Redox & Salinity probe as well as a GHL 4 pump dosing unit. With the Profilux you can get 2,3&4 pump units either stand alone units or controller units.

IMO - The Redox and Salinity probes are definitely fun toys to have, but i don't pay much attention to these numbers anymore. They tend to be highly sensative and wander all over the place. Even the smallest stray voltage will send these probes way out of whack. I personally love playing with reef toys, but unless your running ozone on your tank, these probes really are just that.

I guess I'm really just suggesting that your money might be better spent on something else.

I find that the ORP isn't very responsive to ozone, either.

If I have people over and they are in the same room as the tank, I can see the PH drop, then raise after people leave...think this is atributed to Co2 levels in the room etc...Fun to look at the graphs and compair to what was actually going on in the room at the peaks and lows.

That is kind of what I was thinking as well.
