What water treatment do I need for a saltwater aquarium?

Saltwater aquariums typically require a high-quality marine salt mix, dechlorinator, pH stabilizer, and supplements like calcium and alkalinity buffers. These treatments work together to mimic natural ocean conditions and maintain water quality.

What is the best salt mix for a saltwater aquarium?

The best salt mix depends on your tank setup. Reef tanks often benefit from reef-specific mixes rich in calcium, magnesium, and trace elements, while fish-only systems may require a standard marine salt blend.

Do I need a special water conditioner for saltwater tanks?

Yes. Use a water conditioner made for saltwater or reef tanks to remove chlorine, chloramine, and heavy metals without harming corals or invertebrates. Some conditioners also support slime coat protection for fish.

Do saltwater fish tanks require a special pH level?

Saltwater tanks should maintain a pH between 8.0 and 8.4. Using a buffer or stabilizer helps keep pH within this ideal range and prevents fluctuations that can stress marine life.
