How to measure effluent of Ca Reactor with Ph Controller

I just purchased a Milwaukee Ph Controller and with to use it with my
My Reef Creations CR-4 Calcium Reactor. First, I may be incorrect but
I had the idea that the way these work is they turn off the solenoid
of the Ca Reactor when the Ph drops too low (I have been told it is
6.5). I know I could mount the probe simply in the sump and look for
that to stay around 8.0 but yet I would think it's best to monitor the
effluent. The thing is from what I can see the way the controller
works with the setpoint it turns on the power (to the solenoid) when
the ph goes below the setpoint whcih seems to be opposite of what I'd
want. Am I correct about this?
My other question, like I said how do I measure the effluent? There
is nowhere to hook this into the reactor. The only idea i have come
up with is something like a small plastic cup with suction cups that i
can place in my sump and run the effluent hose into. That way I can
just place the ph probe in that to measure the effluent and it will
flow over the top as effluent continues going into the cup but I don't
know where I can buy something like this but I imagine I can find a
place to purchase the cup and as well suction cups. What are others
doing for this purpose though?

do it in reverse dont get above 6.5 and use your bubble counter to set the low, no harm
to have ph in the 4's though its kinda a waste in gas.

as for where to hook it up ideally your reactor should have a place where it will go, if
not then a cup in the sump is your next best aproach, as to getting one, you can build one
out of acrylic or easily modify a number of things that will allow it to work, including
the plastic cups you can often buy softdrinks in at fast food chains. put a few small
pieces of LR in it, stick probe in, stick output tubing in, put in area lower than top of
sump, but higher than the high level. the cup will overflow and your set.

How do I do it in reverse though? It seems the controller is set to
shut on when the ph goes above the set point, not below.

sorry for not being clear, you want the ph lower than 6.5 not above it. reverse your plan
not its functioning.

hi.
Is the solenoid a NO (normal on) or NC (normal close) valve? For NC, you
need to shut off the electricity to the solenoid. For NO, you do the
opposite.

for a CA reactor for safty safe if its not a NC get one. you also want this off when the
supply pump to the reactor is off not just ph settings.
