dosage of baking soda

[wolf]

Anyone care to comment on the dosage of baking soda ? If I do a 30 % water change, do I need to proportionate the dosage accordingly ? Does it has any relation to volume of water in tank ?

Thanks !

Wolf..measure KH before water change and after water change to see if the KH level drop. Find out how many times you need to do water changes for the KH level to drop and then dose a bit at a time before reaching your desired level..note that do not increase the KH level by 2 in 24 hrs or else your fishes might not be able to take it. After that will you know when you need to add baking soda and how much to add without using the test kit that often liao.

Refernce to this website http://www.drhelm.com/aquarium/chemistry.html :

1 teaspoon of baking soda (sodium bicarbonate, not baking powder!) in 50L of water will raise it by 4 dkH.
