Saltwater FAQs

What’s the best starter fish for a saltwater tank?

Popular beginner-friendly choices include clownfish, damselfish, and gobies. These species are hardy and adapt well to new setups.

Do I need a protein skimmer for my tank?

While small tanks can run without one, a protein skimmer is highly recommended for maintaining water quality in most saltwater and reef setups.

How much live rock should I add?

A common guideline is 1 to 1.5 pounds of live rock per gallon of water, but it depends on your aquascaping style and filtration system.

Can I mix saltwater and freshwater fish?

No. Saltwater and freshwater species require completely different environments. Each should be kept in its proper system.

How often should I test water parameters?

For new setups, test daily or every other day. Once established, weekly testing is usually sufficient to ensure stability.
