i have a 30 gal tank. of which, I estimate 20 gal is water. would I put 40 teaspoons in? sounds like a lot? or am I understanding the directions all wrong?
is there any harm with using kalk to raise the ph of makeup water, etc? or should it always be dripped?</STRONG>
The 1-2 teaspoons of kalk is per gallon of freshwater that you are mixing it in. Generally, most people replace the water that is evaporated from their aquarium with kalkwasser. In other words, if you are making 1 gallon of kalkwasser, use 1-2 teaspoons of kalk powder to mix it. If your aquarium has 1/2 gallon a day of evaporation, you would replace this 1/2 gallon with kalkwasser instead of freshwater. And yes you do need to add the kalkwasser slowly or it can cause a big spike in your tank pH that may be harmful to your animals.
