Over 70% of coral reef surface area is covered by crustose coralline algae, a type of calcified marine alga, highlighting their foundational role in marine habitats. But what are calcified sea algae, and how do these intriguing organisms create their hard, reef-building structures? They are a diverse group of marine organisms that absorb minerals from seawater to create rigid structures that are crucial for ocean health.

A decrease of just 0.1 on the logarithmic pH scale represents a 30% increase in acidity, revealing the dramatic impacts that can occur when the pH gets too low. This seemingly small change can trigger significant problems across ecosystems, infrastructure, and human health.

Calcium carbonate is one of the most abundant minerals on Earth, but its source is often misunderstood. When considering, "is calcium carbonate from animals?", the answer is complex, as it can be derived from geological deposits or animal remains.

According to a 2018 study, kelp can create micro-layers with higher pH levels, demonstrating that yes, seaweed does affect pH in localized water environments. This influence is driven by biological processes like photosynthesis and chemical interactions in different contexts.
