Automatic or manual co2 injection

IMO automatic is the way to go. The controllers & probes are much better
than they used to be. I know people that only calibrate the probes once
every 4 months & they are hardly out. Never seen a sticking valve.

Even with a manual system on all the time you are going to get PH swings
because you are putting CO2 into the tank at night & its not being used by
the plants. Not to mention the plants are giving off CO2 at night.

I'm thinking the automatic might be more trouble than its worth. probe
replacement, calibration, sticky valves.

If my kh is 8dh, I'm thinking of just bubble in some co2 slowly untill
my goal ph is reached, make sure co2 isn't too much, and leave it on
all the time. I would think turning the manual system off at night
would cause ph up and down?

It seems to me (guess) that the automatic system might be on most of
the time anyway.

*if* the tank paramaters remain *fairly* constant I would think the
amount of injected co2 would remain fairly constant also?

Thank you all for the help

Any good? I like the external reactor. I might use my Ehiem 2013
canister filter as a reactor?

I guess if I were to get a controller I would like a *good* one

Thanks

Here ya go.
