say i were to cycle my tank with one filter and then down the road decide that filter isnt working very well or i just want to upgrade. how do i change filters safely without cycling again? reason for my question is that i have a topfin 30 (which i think you already know but if not you know now. haha.) and cant afford to buy the ac70 at the moment. but i would like to start the fishless cycle.

Personally, I would just wait. Look online to see if you can find a more affordable price.

If you don't want to wait, then when you get the new filter, run them together on the tank for about a month. That should help. Once you remove the top fin, it would also help to take the filter cartridge and put it in the tank for a couple of extra weeks,.

i would like to wait just for the sake of being able to be there when its cycling since im going away but at the same time i cant wait just to fill the tank up and get working with it. since i have another week until i go away. but i would also like to see how the topfin works. i don't buy things online. no credit card haha. if i had one id be in trouble...

i wonder if any of the aquaclear media would fit in my topfin... i could just buy aquaclear things and just move it over. it would be nice if it was that simple..

I am not positive about this, since I have a fluval - but I think that AC takes loose media like a canister, and TF takes a cartridge.

okay thank you. i just found out someone is selling an ac70 in my city for $30 but its on the other end of the city lol. but that means i wont have enough gravel.. hmm
