ive been told that i should drip Kalk which is what ive been doing and it works pretty good. as a a matter of my tank has been doing better ever since i started. Some people tell me that they use kalk in their auto top off system rather than dripping. But what i was told by other users and other online forums is that once the kalk is mixed it immediately starts losing its effectiveness and what you make needs to be used within 1-2 days. is this 1-2 day thing a true. because my reservoir is 5 gallons and that lasts about 3 days. i dont want to be dumping kalk in my system if its going to be uneffective.


or should i just suck it up and keep driping it
