Fowlr & ats

[tonychai]

I have fowlr and wanna to have ats for filtration. Do i remove the bio rings?

Welcome from Hong Kong.

Yes. Your sand and rock will do the job that the bio rings did.

Thanks for you reply.

I don't have sand bedding, only live rock. I 'm planning to change to use the artificial rock. May I still take away the bio ring？

[SantaMonica]

What type of artificial rock? Can you send a link to it?

[tonychai]

Korallenwett ceramic rock from germany.

[SantaMonica]

Well the ceramic seems like it will be ok once matured, but why change from live rock you already have?

[tonychai]

I wanna to re-do my rock work to make more cave for the fish and add some Lps. do i cure the ceramic rock add to the tank？

[SantaMonica]

Probably good idea to cure it.

It will be a year before the new rock is covered in periphyton however.
