Hi Taat, sounds like you're getting everything you need.:wink1:
Like Crox said, make sure you adjust the flow correctly. Not to much, not to little. The media in the chamber should just shimmy right above the surface, not tumble.
Also make sure you rinse the media well before allowing it to go into your tank water.
I rinse mine by setting it up in my case the sump, and I have the initial discharge water pour out into a bucket until water runs clear. Then I place the discharge/return line back into the sump. Then I make up a little fresh ro/di with salt and add that to the sumpl.
Minnie water change while rinsing phosar, works out just fine.:sgrin:
Let us know if you need anything else, and by the way you don't really need a 600 pump, so if and when your pump should fail any small pump or power head will do.
