Not really. If you do a 25% water change and your tank is 17 dKH, and the water change water is 10 dKH, the new dKH in the tank will be 15.25.i know i have to do water changes but doing to many in a short time will affect other perameters to quickly
What salt are you using? Are you using tap water?I tested last night my KH was 304.3 and Cal 520 and I don't does at all the only thing I put in is iodine and then coral accel and snow I have a nitrate prob also it seems to stay at 20?? so if you figure somthing out let me know as well
