Cycle question

[btate617]

I have a question for you salt water types....

I have been searching this for the last few days and have been finding different opinions. My question is if you were to seed a filter for a salt tank from a fresh water tank would it work, or would the difference of the waters interfer?
I am just curious. Thanks.

From the research that I've done, a freshwater seeded filter will not seed a saltwater tank. In saltwater tanks, it's the live rock that provides most of the beneficial bacteria.

If you get lots of live rock from a "living" saltwater tank, it will cycle your tank quickly, but I used a shrimp and live rock to cycle my (used to be) FOWLR, which is now turning reef.

The micro organisms that make up the tank's biological filter are different in FW and SW tanks. One cannot "seed" the other. SW filter media, however, can seed a SW tank just like in FW, this is how you would set up a quick SW QT tank.

Thanks everyone. I know about the live rock, But I was thinking years ago I knew a few people who kept just fish in their salt tanks using a canister filter. So I started looking up with the different water chemistry could you seed from one to the other or not.
I wouldn't think you could but many discussions I came across on it were saying you could so I thought I would ask. And to who asked no I am not doing a salt tank, I was just curious.

Difference in salt level will not allow it to work.
