I am about to purchase a 65l litre tank for the little man in the house.
Can I take some of the wool out of my filter and put it into his and then use some of the water from my water change of my established tank?
It has had tropical fish in the tank before as I am getting it second hand.
How long shall I leave it to cycle for using my mature media and water?
I used this method for my 110L tank, with a Fluval 205. I researched then asked the question regarding the media itself... you will probably find alot more of the beneficial bacteria from a donating tank live on the ceramic balls/tubes than the wool itself.
So, what other (if any) types of 'mechanical' filtration do you have? I was lucky enough to be given a complete handful of ceramic balls, which completed my cycle in 12 days.
With regards to the water, there really is not alot of the bacteria living in that,
and besides, the Bacs needed actually enjoy a supply of fresh water, so maybe think about using fresh, de-chlorinated water to fill your new tank.
Once you are happy set-up, temp, substrate (?) and you have completed the cross-over, continue to monitor your water test results, adding ammonia (i presume you are fishless cycling?) and partial water changes as the results depict.
Depending on how mature your existing tank is will decrease the time of your current cycle, but by how much differs across the hobby.. but also, may i suggest the completion of a 'Qualifying Week', i didn't do it fully with my smaller tank and learnt the importance of it.
regards.
Terry.
