 RO/DI Water: Why It’s the Foundation of a Healthy Aquarium

Every successful aquarium starts with reliable water quality. While many tap supplies look clear, they can contain dissolved minerals, metals, chlorine/chloramine, and other impurities that slowly build up and interfere with biological stability. That’s where RO/DI water comes in: it’s widely used by hobbyists because it strips contaminants down to a very low level before you add salt (for marine tanks) or remineralize for specific freshwater needs.

Lighting is usually the deciding factor because SPS generally demands higher light and more stable conditions than many other reef corals. Below is a practical comparison of both approaches, with the pros and cons that matter most, plus the lighting needs reef keepers commonly p ... Read more »

Increasingly, that equation is changing as sustainable coral farming expands—and as aquaculture becomes the industry standard for many popular species. Rather than taking corals from reefs, aquaculture nurseries grow corals in controlled systems, then supply fragments to hobbyists and retailers. The approach is gaining mo ... Read more »
