Frag tank filtration question?

[Mrsalmon]

I'm starting a 20 gallon AIO frag tank (no sump)mostly I'll be keeping softies like Xenia,Kenya tree,gsp,mushrooms,zoas,and leather.

My question is what should I use as filtration (I'm not planning on skimmer)
I'd like to keep a six line wrasse to help with worms and stuff.
I'm planning to use filter floss , and live rock rubble/ceramic rings/coral rubble.
My country have problem with importer of chempure/purigen so I can't use that


Should I use live rock rubble or ceramic ring or coral rubble?
If not what should I use instead?

If yes should i seed my rocks/media by putting it in my main tank?

How should I cycle it, is using a piece of shrimp okay?

I would just use some rock as the primary biological filter. Either place the frags on these or put them under a rack. Keep it simple... As far as cycling the tank goes you might want to place some of these rocks in your main tank for a few weeks beforehand. A nice population of beneficial bacteria will have been established and you should be good to go from there.

If you do keep multiple types of corals, particularly leathers and Kenya Trees I would run carbon.

I have a 25G rimless tank and only have a powerhead, heater, and AI Prime. I do weekly water changes and occasionally will run carbon. I currently have birds nest, Kenya tree, hammer coral, utter chaos, a large dragon-eye piece, and Galexea. Everything has been thriving for about 6 months without any issues.

My fish include an ocellaris clown, Fire Fish, and clown goby.

I also have a significant clean-up crew and only feed when necessary.
