Hey folks whats the best way to swap filter media over to my new tank? A friend has a 85 Gallon tropical tank and hes all for it. We just need to know how to go about it. I tried searching wasnt really able to find a good answer.
If your friend has a really mature external with plenty of media then its really his choice - probably the bacteria is mature enough in the ceramics basket etc. that he could swap the whole sponge for a new one without getting a mini-cycle. He (& perhaps you if you are over there with him) should just make a judgement call on whether the sponge seems to be a big significant part of his bio-filtration -- be sure to ask about the time-line for his biomedia (eg. you wouldn't want it to be the case that the sponge was mature and he had only recently added new ceramic or other media in another basket - you wouldn't want him to get a mini-cycle.) But as I say, if its all mature then I would think you buy him a new sponge, take his whole sponge in water and then, yes, cut it in half for your two filters you are going to fishless cycle, if I'm reading your plan correctly...Ok after talking to my friend again we came to this. We both have 3 stage external filters. Hes willing to give me the whole foam pad and i will replace it for his tank. Should i cut it in 2 and put half in each filter? Currently im only running one 110 Aquaclear filter and there is a second there waiting to be used for my 120 gallon.
