New Tank

[Billvyx]

hi

i own a juwel rekord 800 and have recently got a rekord 600 and i was wondering if putting one of the sponges from the filter in the 800 into the new tank will be good for the water. i have added some of the water from the 800 to the new tank already as i thought it could be a good idea. if it is something i should do which sponge would be the better one to swap?

thanks

Swapping the water will have hardly any benefit.

Provided the 800's filters have been in several weeks, transferring one to your 600 will be wise. Ensure you don't transfer more than one however, you need some good bacteria to remain with your fish...

Whenever you donate biomedia from a running tank that has a fish load, you should attempt to preserve 2/3 of the biomedia for the existing tank. Can't tell you how to do this with your particular sponges or whatever but you may just have to be creative to figure out what would work. Adding mature media (filter media like sponges or ceramic rings, ceramic gravel, bioballs, whatever) to a new filter that hasn't been cycled is the only significant way to transfer beneficial bacteria. You have to have the environment ready for the new bacteria coming in: Ammonia and raised temp etc. if moving it into a fishless cycling tank, a load of fish if moving it into a fish-in cycling situation (which of course is not considered a good situation by comparison.) Have you read our articles on the Nitrogen cycle, fishless cycling and fish-in cycling in the Beginners Resource Center?
