Help, I just bought a used tank off of Craigslist and the prior owner totally threw away all of the old filter media.

Is it possible to use the rocks that I got to help along the cycling process or do I have to start at Square One? I wasn't going to use the large pea gravel that he gave me, but if it will help the cycling process I might.

Thanks

Depends how long the stuff has been out of service. It would help to use the rocks definitely. Put the gravel in a bag or something to make for easy removal when cycling is complete.

If you have another tank with an established filter you could use that one to seed the new tank. I do it all the time. If I get a new tank I buy a new filter for the old tank and put the old filter on the new tank. Or borrow media from the old filter.

Or if youre lucky like me itll take a week to cycle with just ammonia. Not sure how I did it but I did. And the tanks been going fine for a few weeks now...0 ammonia; 0 nitrites.

It took me 3 weeks to do my 90 gallon; and a week to do my 55.

:? I'm no cycling expert, but from what I understand, without any type of established bacteria being used to seed the new tank....that's not possible.

AND FYI I didnt swap over any sand, rock or filter media from my 90 to the 55. My 55 has new PFS, new holey rock, new water and a new Eheim 2217. :wink:

Oh and when my 1st tank took 3 weeks to cycle some said that was too soon too, but its been fine over a month. 0 ammonia, 0 nitrates.

:popcorn:

Yeah if it wasn't kept wet and dried out I wouldn't say it would work. I used old substrate from a cycled tank, then put it inside a bag and stuck it in my fx5. I cycled a 125 in a week that way. I have a 55 that I am just about done cycling from square one using the dry biozyme in the yellow or red containers. I set it up 10 days ago with a Cascade 1000 and a cheap HOB that came with the tank. try that stuff out I cost like $3. it worked for me. :)
