RE: Carbo Plus

[Scheele Juergen <juesche at earthlink_net>]

John,
I may find "heavy resistance" here on the list by saying that
CO2 and in particular the "Carbo Plus" unit is not there for <lowering>
the pH !
You can "adjust" the pH with CO2 slightly, others on this list
may elaborate further on this, but the main point is,
check your parameters, something is wrong !
KH bigger then GH is a big no, no !
KH should always be 70% - 80% of the GH !
Give us more info.
Where is your water coming from ?
Parameters?
Do you treat your water?
There is a discussion going on how the CO2 is produced in the Carbo Plus
unit and if its
different then "Bottled CO2"
As a matter of fact, the manufacturer of this unit states clearly (and
thats the only clear statement)
that it will "lower the KH if you have a medium KH" ????
Well, maybe it has lowered your KH into a lower range ?

yes, i too have noticed that the carbo-plus has a hard time lowering
pH.......i run mine at about five green bars for the 11 hours that the
lights
are on and the plants are doing wonderfully (i can even see them
pearling in
the evening) so i assume there is enough CO2 in solution....is this a
wrong
assumption? (though when i meassure it with a Lamont CO2 test, it comes
out
as 8ppm, a bit low right?) my pH is currently 7, so i can live with
that, and
my fish and plants seem fine with it too....my carbo unit is simply in
my
tank right under the outflow bar of my cannister filter...

anyone else?

my tank-
pH - 7
KH - 4
GH - 2
90 gallon
200 watts of pwer compacts
