Returning to hobby need updated guidance

[Shobloth]

Hello all,
Been a few years but covid finally led me back to the hobby this time with my kids.
I have a 40g innovative nuvo with a kessil tuna blue light. Vortec 10 if needed and live rock in the front (lots). Salinity is 1.025. Water is 2 days old.

What's missing:
No idea what to put in the back for filtration.

I have: (but have not put in)
porous "œballs" that look like live rock
crushed coral substrate and no idea how to use
Black sponge like innovative filters with a housing and light
Lots of small live rock
Bucket o carbon.

Do I need a snail urchin starfish or shrimp yet?

Objective: Rockin Lps corals with a clam and maybe a fish or 2

I am considering offloading the tuna for a new g5 radion 15.

Feedback on anything is appreciated.

If you are using live rock inside the tank, leave the back for a protein skimmer and a bag with carbon. Wait a couple days to see ammonia and then Nitrite spike to check the tank is cycled. Order a saltwater test kit off of Amazon for PH, Amoonia, Nitrite, nitrate. Also i'm guessing you added "œlive rock" that had dried out. That means they are no longer live so Amazon also has a product called Instant Ocean Bio-Spira, buy the 75 gallon one and pour half in the first day and half the third day and you will be set! The light is good enough, that is a great light. Simple really, the bio balls that look like live rock could be used if you want to keep a lot of fish but are unnecessary with a large amount of live rock.

Good luck
