Middle chamber- TMC 30L

[Lilchef]

Heya. I currently only have the sponges that came with the tank in the middle chamber and some rowaphos in between them. Do I need to have more in there? I keep reading about filter floss and power pads and things and I'm wondering if I'm maybe missing out here!

id ditch the sponges to be honest mate, they are a nuisance once they populate with bacteria, you'll get a build up of nitrates which will upset corals and feed nuisance algae.
Just use some floss and the rowa in a filter sock, and rely on liverock for filtration

What he said lol except I run carbon in a filter sock too

[Lilchef]

Do you literally just grab a handful of filter floss and stick it in the chamber? Might have to get some off eBay then! What does the carbon do?

Carbon is used as a final polisher to improve water clarity. Due to the way its made it has a hyge surface area that has a charge, this attracts and locks in pollutants, you do have to change it quite frequently as it can exhaust quite quickly.

Sounds good, I may have to invest in that too then!
