Just wanted to say hello - I am not new to the hobby. I have tried saltwater about 15 years ago in my 75 gallon and kept having issues so I tore it down. Now my 75 gallon runs beautiful sevrums that keep breeding. Now I have a 55 gallon I am setting up to start a cichlid tank and I wanted to try to start my saltwater so I bought the fluval evo 13.5 I was unhappy with several things so far so I have done several upgrades . I am on my third week of running it. Anyways just wanted to say hello
