Hi I’m currently 4 weeks into the saltwater hobbie and I’m a complete newbie I have the Fluval evo 13.5 g with 2 clowns everything is starting to settle parameter wise just have a problem trying to remove small particles from the tank possibly from the substrate when I done a water change I have just the stock return pump and stock filter media box with a poly filter just wondering on any suggestions to tackle the cloudiness/small particles thanks.
