Hi everyone! New to reefing so figuring this stuff out as I go, I have a 2mnth old cycled tank with a few fish. I purchased a 100g system second hand and set it up how it was.
After a bit of research I don't know if the media provided is the best way forward. I'm in two minds to leave it and see how it goes or would it be easier to rectify now.
I have attached 2 pics of the start of the sump. The inlet goes in through a mech filter pad, the first chamber has a big bag of crushed looking rock.
The second chamber has a smaller bag of ceramic noodles and a bag of carbon.
Third has a sandbed and chaeto.
Last is return and external skimmer.
Should I change the media bags or are they ok? Should I add a marine pure block somewhere? In the baffles or a big one in a chamber?
Thanks in advance.
