Hi Joe.
Well done on the upgrade. The BM will be much happier in a 90ltr than in the 13ltr, but I'm afraid I still have some bad news.
1) Goldfish are messy fish and should really have filters designed for at least double the tank size to cope with all the waste, so even your new filter will struggle.
2) FK recommends a minimum of 30gal/137ltrs/36 US gal for a single fancy goldfish (75ltrs is 20 US gallons, btw). This is because anything less than that can result in stunting. If your GF has had the B, for a few years, the chances are, it's already stunted.
Please see these links for further advice:

Once you get an even bigger filter, you can do the same again and put the media (sponge/bioballs - whatever's inside the filter) into the bigger filter.

Any more qyuestions, just ask.
