I just set up a tunze calcium reactor and have a ph controller and regulator and sylanoid. should I put the probe in the aquarium or to measure the effluent out of the reactor?

PLEASE HELP

You want to measure the effluent Ph either in the reactor or a seperate cantainer that the effluent feeds into, not the tank although you shouls also be moniroring the tank Ph as well. I feed the effluent into a small cantainer that holds the probe and the effluent tube placed inside my skimmer...

I was going to do something similar to Mitch, but the method Jim suggested is just as effective.

Here's an example of what Jim was describing on Melev's tank:

Yes. If that is the tank PH. Your PH is one of the most critical items to keep stable. It doesn't have to be a perfect 8.4 but it needs to stay relatively fluctuation free.

If you are swinging .6 from day to night I would be looking into alternate methods. I run a large light over my fuge 24hours to offset any swing from CO2 exchange at night. Using a quality salt mix with good buffers in it will help prevent swings but you must make regular water changes of a decent percentage or the buffers will get used up.

Mike, what are you using for your fuge light?

my tank gets up to 8.2 at the end of the light cycle. I have a fuge that has been running 24/7 but I am trying to change it to a reverse light cycle. With a .3 swing, is there an issue
