I got KH/GH and pH test kit from Hagen, and the readings a

Temp.= 28.6 °C (about 80 °F)
pH =7.6
KH=2.8 dH°
KH (ppm)=50 (the manual says to add as many drop until change color, and
multiply the number of drop by 10)
CO2 = 2.11 (an excel worksheet calculates the amount of CO2)
GH(ppm)=240 (the manual says to add as many drop until change color, and
multiply the number of drop by 20)
GH= 24. fH°

is it normal the GH been so high ???? how can I make it come down ????
I read in the tropica web site about adding sodium bicarbonate Success with
planted Discus aquaria - part 2 I should increase the KH to about 4 to keep
discus, but discus are from soft water and the GH I think is too high will
it increase the GH if I try to increase the KH ??????? , I haven't done
anything because I am not sure because this is a new setup I'm trying.....it
has been 3 days with gravel, water and the filters runing like crazy !!!!
NEW!!!

Thanks

it sounds like you are planning to get discus?

I keep mine at KH=3, GH=3

so I think your KH is fine probably (dosent matter...see below)
but your GH is way to high (this is just like my tap too)
if your GH ppm is 240, I'd say your GH dH is 14.
There aren't to many ways to lower GH, the best is RO treatment,

(this is the see below part)

if you plan on keeping discus happily you need to get an RO filter, and then
treat the RO water with baking soda(bicarbonate) to raise the KH, and then
just add a little plain tap water to supply the GH (cheap & easy, but you
could use RO right or discus buffer, etc).

I found though that RO really doesn't effect the pH as strongly as one might
think, so you will probably have to add a pH reducing acid (pH down is
pretty cheap if you buy it in large bottle). Shoot for a pH around
6..Amazon Sword and Wisteria (sp?) are fine in this low pH, I guess some
other plants could handle it too.

also raise the temp 2-4 deg F
the above is _only_ for discus.

now...if you want to keep African Cichlids....well, just add some baking
soda, and your water is perfect
