I'm a beginner in DWC and I just built my first 2 DWC Tanks.
After this, I ordered all the needed stuff I needed. HESI Starterkit ect
Now, I'm facing the problem, that the PH is raising every day for about 1.5 - 2.
I really have no Idea what to do. I putting every day PH Down to it, and for the Moment it's good, but the next day, when I come home and check the PH, it's back at 7.5 or higher. (I'm correcting the PH every time to 5.5 - 5.
Do you have a idea, what could cause this Problem?
I'm using normal tabwater...
