so I added an Avast marine kalk stirrer to my system last Tuesday. My ph ,as with most tanks, goes down at night and up in the daytime. I set it up to dose around 100 ml every 2 hours with a brs dosing pump starting at 6 pm and ending at 8 am. The total amount dosed is around 1/4 gallon to start. My ph used to run from around 8.1 to about 8.3. It now runs from around 8.28 to 8.39. A few times it has spiked to 8.41 or 8.42 during the afternoon. I tested my alk and calcium after 4 days and they were spot on at 8.2 and 430. My question is, is it a big deal for my ph to be spiking about 8.4 for a short period, about an hour, some afternoons or am I just getting worked up over nothing? I have attached screenshots of before and after adding the Kalk stirrer. Thanks for your help!
