After ignoring my tank for about a year, i have just started to restock my tank. My current tank total volume is around 600L, and i run a calcium reactor. Until recently someone pointed to me that my PH of 7.7 is extremely low and need to look at. I currently run a calcium reactor and i attribute this low ph to the calcium reactor. So in a harsh move, i decomm the calcium reactor and switched to Tropic Marine All-For-Reef dosing. True enough, the ph went up to 7.9 in the day, and around 7.8 at night. To further increase the PH, i decided to add in a kalkwasser reactor to dose at night. I use a kamoer continuous dosing pump and i drip 5ml/min of kalkwasser into the sump at night. The total volume of kalk for the overnight dripping works out to be around 5L/night. However, i don't see a dent in the ph at all. May be a 0.01 or 0.02 increase in ph.

Since i only started doing this in the last 1 week, do you think the PH will gradually improve over the next few months if i keep doing the kalk dosing at night? Or would it just stay like this?

Look at getting a co2 meter from amazon. Measure inside and outside the house. Also consider using sodium hydroxide drip instead of kalk to bring ph up.
