It sounds like you are concerned about watching your pH and you should not be. Yes, you can cause your pH to spike if you add Kalk too quickly....but you are allowing it to drip in which will prevent that from happening.

You can't determine the correct amount of Kalk by checking pH. You need to be checking Ca and Alk. (particularly Alk)

So...are you adding too much? We can't say because we don't know your Ca/Alk levels.

Add your Kalk every night as you are doing. Take Ca/Alk readings at a set time each day. If the levels are falling, you need more Kalk overnight. If the levels are rising, you are adding too much. pH will tell you nothing.
