Why is it important to maintain proper pH levels in an aquarium?

Maintaining proper pH levels in an aquarium is vital because pH directly affects fish health and the availability of essential nutrients in the water. Fish are sensitive to pH fluctuations, and deviations from their optimal range can result in stress, impaired physiological processes, reduced immune response, and even increased susceptibility to diseases. Furthermore, pH influences the solubility of minerals and nutrients in the water; certain nutrients are more available at specific pH levels, impacting plant health and overall ecosystem balance.

If the pH is too low (acidic) or too high (alkaline), it can hinder the uptake of vital nutrients such as calcium and phosphorus, which are essential for growth and reproduction. Therefore, sustaining an appropriate pH is crucial not just for the wellbeing of the fish but also for maintaining a balanced ecosystem within the aquarium.
