Default CO2/PH/KH Relationship

I imagine the SA will get used to the moderately hard water. I won't put the
peat in then.

Thanks!

Plenty of those soft-water South American rivers have both apistos AND
plants, so don't worry about it. Most apisto tanks have plants to help

give
the fish a secure feeling. Pure breeder tanks with bare bottoms obviously
will not. But again, most community-type apisto tanks do have plants.
Conversely, most African Rift Lake tanks, which are hard and alkaline,

have
NO plants. That is mainly because those type of fish like to dig and dine
on plants. To sum up, I think the type of water you have will dictate the
type of fish you keep, and the type of fish you keep will dictate plants.

I
say enjoy both!

Yes I was referring to using it in the aquarium filter to soften the

water
for the fish -- apistos, rams and tetras. But, I'm hearing here that

plants
like hard alkaline water! What a dilemma!

1) Will filtering with peat help the plants?

2) Will the peat affect Co2 calculations using the PH/KH? I know
phosphates
will.

Depends what you mean by peat filtering. I prepare the water for my

tanks
through a peat filtering rig I built - makes me about 50USG at a

time -
I
use ordinary garden peat. What I found wast that after the initial

filtering
there was massive (100-120ppm) amounts of CO2 in the water which then
disperses over time as you'd expect.

Therefore what I do is measure the KH as its working and when that

comes
down to where I want it (about 5 DKh) then I stop the thing and then

just
circulate the water till the initial blast of CO2 has worn off.. WHat

I
then
find is that the relationship between KH/PH & CO2 levels seems to work
perfectly well. i.e. the Ph has beeen reduced along side the Kh by a
predictable amount.

When the water is in my tank the PH is then reduced further via CO2
injection - the KH is stable.

If you were referring to using Aquarium peat in your filter then I

have
never used it so can't help - although I would think the effects would

be
similar though maybe less dramatic.
