Is it good to use a fluval 405 in a 30 gallon saltwater tank?

Using a Fluval 405 can be suitable for a 30-gallon saltwater tank, but it has some limitations. While it provides mechanical and chemical filtration, it may lack the biological filtration capacity required for a marine environment. Additionally, saltwater tanks typically benefit from protein skimmers and specialized filtration systems designed for saltwater. Ensure proper maintenance and water quality monitoring to maintain a healthy marine ecosystem.
