Re: [APD] Milwaukee vs Pinpoint pH Controller

["S. Hieber" <shieber at yahoo_com>]

The Milwaukee trips ON at 01. units up and Off at 0.1 units
down.  For example, if you set it at about 6.8 pH, it will
trip ON at 6.9 and OFF at 6.7. So your spread is about 0.2
units or about the same as you have over the course of a
day using no controller at all. With that in mind, you
might consider skipping a controller altogether.

If you interset is in saving CO2, you can get a decent
solenoid for about $30 from Customaquatic.com and hook it
up to your lights timer so the CO2 doesn't run at night
when it's not really needed.

Or you can just let the CO2 run 24/7 and expect a pH shift
of about 0.2 units over the course of the day.


The Milwaukee is a reliable unit although less precise than
the Pinpoint -- but certainly clsoe enough for aquatic
gardening purposes.

Good luck, good fun,
