Maintaining proper pH levels is crucial for aquarium health as it affects fish physiology, plant growth, and biological processes. This comprehensive guide explores pH management in various aquarium types.
Understanding pH:
Basic Concepts:
– pH scale (0-14)
– Logarithmic nature
– Daily fluctuations
– Buffer systems
– Testing methods
Optimal Ranges:
Freshwater:
