pH too low: when raising it does and does not fit

Do not raise pH automatically. Low pH can fit an intentionally designed bee setup, while an unexpected decline elsewhere needs investigation. Consider the trend and actual species, rather than a general minimum.
Three checks before adding anything
- Confirm the measurement. Test KH and compare with source water and previous readings.
- Check CO2 injection, surface movement, filter operation and unusually large amounts of decaying material.
- Establish whether active substrate or acidifying materials are an intentional part of the setup. Exhausted substrate does not automatically explain falling pH.
In a Neocaridina system with inert substrate, confirmed insufficient buffering can justify changing water preparation. A suitable GH/KH product may be part of that recipe. Prepare and test outside the tank. No fixed KH produces the same pH in every aquarium.
Do not repeatedly add KH to substrate selected for an acidic bee system without reconsidering the whole approach. Crushed coral also does not dissolve predictably from one universal dose. When animals are in acute distress, promptly check oxygen provision, ammonia and nitrite rather than waiting several days for a better pH trend.
