🔴 Ideal pH Reached (Acidic pH) and KH (carbonate hardness)

Finally, I managed to stabilize the pH. Knowing about things like Kh (carbonate hardness), the pH of the tap water, how an aquarium matures, etc. - all of this made a difference. The use of products like acid buffer, alkaline buffer, and discus buffer helped and hindered at the same time because I didn't know exactly how each one worked, or what my water was like. I still use the acidifier, barely use the alkalizer (my water already has high Kh), and practically abandoned the use of the discus buffer (phosphate-based buffer).
