Read the article but still not getting the answers(all the chemistry equations is getting me no where). Can someone pls help...

1) ph LOW, ca LOW, dkh OK

use PH buffer + calcium additives

2) ph LOW, ca LOW, dkh HIGH

use PH buffer + calcium additives

3) ph LOW, ca OK, dkh OK

use PH buffer

4) ph LOW, ca OK, dkh HIGH

use PH buffer + a little calcium additive when it reduces

ca and dkh depletes together, so if both are alrite, or both are low, use only kalk solution to maintain them or boost them respectively.

kalk solution will help to maintain your PH so if all three are low use kalk solution to boost them....

note: do not alter them drastically, do it slowly over a few days....

Be careful with the use of PH buffer if I may add.

Because some PH buffer raise alkalinity as well.

IMHO, get cal and alk in balance first and then tackle the PH issue after that.

Many factors could contribute to low ph :-

- low alk

- high co2 indoor

- the use of calcium reactor

etc...

Another good Randy's article on ph

http://www.advancedaquarist.com/issues/june2002/chem.htm

With the cal/alk in balance, dripping kalk would be useful to get a healthy ph reading in addition to your normal routine cal/alk supplements.

my 2 cents

Thanks for all the good advices. I'm understanding it better now. One last question, any specific ph buffer product that does not affect alk?

again.
