i have a aqua-internal 200 filter in my 60 litre tank
When I need to replace the cartridge what’s the best way without losing good bacteria
There no room in filter to put old foam in cartridge
And do not have a spare filter to run along side

Don't put the cartridge in, replace it with filter padding. I know you said you dont have room, but you would if you removed the cartridge. I'll look it up and give other advice. If it was a hob I'd tell you to put filter padding on the intake. If you can maybe tie it up. On there ill look up your filter and give more later.

Hello Molly...

Don't worry. Some bacteria will be lost, But, there's bacteria living on all the surfaces inside the tank. Change the filter when you do your weekly water change and rinse the new filter in some of the old water. Put the filter back together and start it up. The bacteria that's lost will be replaced in a few hours.

Remember, keep up on your water changes. Keeping the tank water clean is the most important part of the fish keeping hobby.
