Crushed Coral as filter media

[RSanders]

Could CC be used as media in a canister filter?

Two reasons for the question.
Firstly, I have seen it used in RO/DI systems so I'm thinking it does have some use for filtering. It also seems like it would grow some bacteria which could help the overall water quality in the tank. Yes/No?
I have read somewhere else about folks using pieces of LR in there so thats what also sparked the thought.
Secondly, I have two Mag350's that came w/ my used setup and I'm really just trying to find a use for them. Right now I have them both empty to just move the water. My fear is that I'm using alot more power to run these than two MJ900's which I also have.

Any thoughts?

No it is not a good idea. Live rock and sand should be your primary filtration.
Never saw CC in a RO/DI unit before..??

As previously stated, Canister filter is not recommended to use with reef tanks regularly. The canister is recommended to be used to polish water occasionally.

That being said, Yes, CC can be used as canister filter media. It will substitute the ceramic disc that usually came with the canister unit. It, however, cannot be a substitute for the charcoal section. CC lacks the absorbing ability as the Activated Carbon. Since most CC size varies, if you want to use them in your canister, you should use them in conjuction with a filter pouch, or make sure the loose small fragments are screened out first.

Also depending on the type of tank you want to use the canister with, CC are not to be used for freshwater tanks that requires soft and slightly acidic water.

DOH!

You're right. Bad memory I guess. After reading this I went to find it and realized it was the Coconut Carbon (Crushed Coral!? NOT).

Thanks for the insight.
