, although certain fish may require higher or lower levels.
What causes high pH in fish tank?
Common Causes of High pH
Many biological processes can interfere with your aquarium's pH. Decreases in pH are more common, since more activity, including algae, fish and invertebrates, dumps more hydrogen ions into a solution. Most of the time,
high pH originates from your source water
.
Will plants lower pH in an aquarium?
