Switching from an HOB Disposable Cartridge to a Biological Filter

[codewon]

Hello, I am fairly new to saltwater aquariums and I am upgrading my tank and filtration. I‘m currently using a TopFin power filter (which has disposable cartridges) and I am switching to a biological filter. How do I get bacteria from the cartridge into the new tank filter?

I’m not sure if this can even be done but I have only been doing this for a month.

Thanks,
codewon

Do you have rock in the tank?
Is the tank cycled?

If so, you already have bacteria present and dont need to worry about saving the filter cartridge.

I have live rock and the tank is cycled.
Thanks

google "the berlin method", this explains how biofiltration works in a reef tank.

Biofiltration doesn't come from a cartridge, it comes from live rock and flow.

It can come from a cartridge if his goal was to seed a sterile tank.

What do you mean by switching to a biological filter?

Im assuming the OP is changing from a filter with a carbon/felt insert (mechanical) that you would throw away when spent, to a refillable media style HOB filter (mechanical and biological)

Ah yeah you don't need any biofilter media in the hob. Just a filter pad, QUALITY carbon, and then whatever else (i.e. phosphate remover).

You can stick your old cartridge in your new media for 5 days and then toss it if you like your bacterial blend. Otherwise, your cycled aquarium will seed the filter media in time, just feed lightly for 2 weeks. You can also seed with Fritz Turbostart 900. I can’t recommend any other bacteria starters for media, as all others have caused problems. Or you can supplement the aquarium with Microbacter 7 for 2 weeks.

Agreed.

Mine is just full of 3 stage mechanical foam at the moment.

Ok thank you!

Removing the filter pad and exchanging it for other media will have the same affect on your tank as when you replaced the filter pads.

I think biomedia is best used to "seed" new tanks or QT tanks. So it isn't useless, but you don't need it since rocks and sand do the same thing.
