Testing Water.

[rdd1952]

Here are their directions from the page you linked to which is exactly what I had already said to do:

1) Rinse the measurement vial several times with water you are going to test and fill up to the 5 ml-mark. Dry the outside wall of the vial.
2) Add reagent drop by drop. Shake vial gently after every drop, until the color changes from blue, via green to yellow.
3) The number of drops used from the reagent corresponds to the existing carbonate hardness (in °dKH). E.g., 5 drops=5°dKH.

Ok i did like this.I dropped like 13 drops before turnig into yellow. What does it mean.

 

[rdd1952]

It means the carbonate hardness of your water is 13 degrees which is about on the border line of medium hard to hard water. It means you have good buffering capacity so your tank water pH should stay relatively stable. It also means that you should try to stock your tank with fish that prefer medium to hard water. Have you tested your pH? Usually, high KH will also mean higher pH.

Here is a site that explains it in fairly simple terms without getting too technical.

U mean the water is fine. Then y are i am loosing these huge amount of fish i have mollies in my 29 gall tank. No i didnt i will test it soon, they dont they have any relation between them, i mean between KH and PH.

How long have you had the tank set up?
How many mollies are in it?
What are your readings for ammonia, nitrite and nitrate?
What chemicals are you adding to the tank?
How often are you doing water changes?
Are there any signs of disease or injury on the fish?

Normally, I would say that the tank isn't cycled but since you have been a member for more than six months, I assume that you have had the tank set up for a while. Really, the GH & KH of the water is relatively unimportant. For mollies, actually that is a good KH as they typically like hard water with a higher pH and also some salt in the water.

I had my tank setup from 1 dec 2006, I have 5 mollies in my tank. I am not adding any chemical to my tank. I do weekly 50% water change and add salt. No sign of disease niehter injury on my fish. Only when they die they will have some white spots.
