Author Topic: cycling using filter media from old tank Q  (Read 9556 times)
« on: January 14, 2008, 05:12:47 PM »

Hello all,
I was wondering if somebody could help me out. Im trying to cycle(with out fish) a new 20g tank at the moment,feeding it fish flakes. It has been running for 5 days now with very hight nitrate readings. I do daily 10-15% water changes.It has new gravel, plants, slate, driftwood and airstone. Both of my tanks have juwel canister filter with 2 blue sponges,green sponge,carbon sponge and filter floss. My Q is, if I was to swap one of the blue sponges in my oldish tank (4 months running) for the new one in my new tank would it disturbed the bacteria living in old tank to much and cause a crash? Or could I use the old filter floss instead and it would do same job? also I have added the kick start bacteria stuff to new tank.
Thanks for any help  smile

You can swap some of the filter media around no problem..... but you also need to put a fish or two in the new tank to keep feeding the bacteria.

Fish food isn't quite the right stuff.  You need ammonia, and fish food doesn't have any.  Fish waste does.  What sort of kick start bacteria stuff have you added?  If you really don't wan to add fish yet, use PURE household ammonia.  But honestly with a filter media swap, you could safely toss in a small # of fish.

Put me back out to sea to play with the fishies...I don't belong on land!  [img width= height=" border="0][/img]

Thanks for answering my Q! I used Aquarium Pharmaceuticals Stress Zyme "Improves the development of the biological filter and helps clean a dirty aquarium."  Im trying to start a dwarf puffer tank so I didnt want to cycle with a fish or fishes becuse then I would be stuck with them. But its great to know I can do the filter thing no prob. I havent tried looking for ammonia yet but I guess if it dosnt sort its self out after the swap i'l have to give it a go! Thanks again proud

lara, i have juewel tanks too. I swop the filter material around to start a new tank off. I tend to clean out my sponges ( rinse them in tank water ) once a month, but if I am starting a new tank, I let the bacteria build up , then swop over a blue sponge and the top filter floss to the new tank and replace it in the established tank with the new ones. It has worked for me, along with checking the water and regular changes.

I used Aquarium Pharmaceuticals Stress Zyme "Improves the development of the biological filter and helps clean a dirty aquarium." 

Using the media from an established filter is all you need.  In part the sentence is reassuring information to a hobbyist.  In part simple advertising schmaltz.

Stress zyme helps how?  what does it do to clean a dirty tank?  or how does it help establish a biological filter?  It keeps morphing.  The hype several years ago was the aloe vera to help sooth and heal fish. 

It is primarily a water conditioner.  An additive to eliminate the chlorine and chloramine from your water supple.  All the other stuff is interesting.  A simple water conditioner and routine cleaning and maintenance will do the same thing.  And, simle water conditioners are usually far less expensive.

You mean aloe vera dosnt really sooth fish! all that wasted money spent on water conditioner with added aloe vera Sad  was your opinion on other products and conditioners made with 100% natural herbs? waste of time??
Thanks Sully
