Hello,
I have been looking around at many sights trying to find what all would be involved in switching from an HOB Aqueon Filter to a Cylinder/Canister Filter. I have a 10 Gallon tank and the filter I currently have is the one that came with the tank. I know about the nitrite cycle and that just simply switching out the filters has a high possibility of killing my fish. Any advice would be greatly appreciated!
On a side note the filter I'm considering on getting is the Tom Rapids Mini Canister Filter.
Thanks! :)

Great filter choice! Simply take your sponge out of the plastic holders, cut the floss of your cartridge and pour the carbon into a stocking an place that all in the new filter with the new media. You could also run the two filters simultaneously for three weeks but I would just transfer the media.

Thanks! That seems simple enough, although I keep hearing about the filter sponge but I don't know where that is on the filter. Is is normally above the impeller? I only started hearing about the sponge when I began looking into switching filters.

Aqueon uses a proprietary cartridge, much like many other hob filters. That blue grid media holder is supposed to provide a place for nitrifying bacteria to grow, as if they know that, and allows you to change the mechanical filtration out without affecting the bio filtration, in theory. This is similar to the frames on Whisper filters. IMO both of those filters suck. AquaClear hob's have the sponge & such as stock media, though you can fill them with pretty much anything.

I'd toss the Aqueon media in the canister, toss the blue frame in the tank where there's some water flow for about a week. Fast the fish for a day before the switch, feed lightly for the next week to avoid any cycling issues.
