Ok for me in a community type discus tank. I’d want about 1000gph in water movement. For media sponge is my main media. For a 120 I’d use a wet/dry filter. 1041AA2E-8A92-4580-9461-AC9CA681E710.jpg. And a odyssea 350 internal filter with 2 sponges in it. You want 2 filters so if one fails the other is working.
That’s how I would run that tank. I’ve got no clue what burnt ceramics are. But good to see even in India they’re selling useless stuff. Everybody’s trying to make money. Sponge that’s all you need. Main reason both canisters and hobs come with sponge. For that tank an fx6 type filter with just the sponge it comes with is all you need. If you’ve already got the ceramics add them to the second cage. That’s more than enough. Second filter the odyssea. For hob the tidal 100. Use the media it comes with and add filter floss to the top and as a second filter the odyssea. Thing is these are discus you will be changing lots of water.
