The Fluval Edge filter A595B is a standard Hang On Back filter which services the 23 litre (6 US gallons) and the 46 litre (12 US gallons) 'Edge' tanks from Fluval.
After taking a look at this filter I'd consider it to be perfect for the 23 litre tank but too small for the 46 litre tank (if you're seeking to achieve a full cycle) as it holds less than 200g of Biogravel.
If you are only expecting to have 0 ammonia and 0 nitrite then it will be fine for the 46 litre tank - see notes about the FULL cycle below.
It is easy to upgrade and is well made - it seems to be available Worldwide so hopefully this upgrade video will be useful for you if you own one of these filters.

A full cycle is completed by bacteria - the aerobic part of biological filtration which processes ammonia to nitrite and nitrite to nitrate followed by an anaerobic part which processes nitrate into soluble nitrogen which bubbles off to the atmosphere.
Therefore it requires a suitable amount of excellent quality filter media to be able to provide the environment for both aerobic AND anaerobic bacteria - that is what Biohome ultimate does perfectly but even with such good media there are limitations and we recommend the following amounts for different stocking scenarios:
(1 US Gallon = 3.8 litres)
(1kg = 2.2 lbs)
Average community tropical aquarium = 1kg per 100 litres 
Average coldwater aquarium = 1kg - 1.5kg per 100 litres
Predator aquarium = 1.5kg - 2kg per 100 litres
Large cichlid aquarium = 1.5kg - 2kg per 100 litres
Malawi / Tanganyikan aquarium = 1.5kg - 2kg per 100 litres
Marine aquarium = 1.5kg - 2kg per 100 litres
Average mixed fish pond = 1kg per 200 litres
Average koi pond = 1kg per 150 litres

You may be disagreeing with the above figures but remember that they are for a FULL CYCLE not half a job - achieving 0 ammonia and 0 nitrite is quite easy since aerobic bacteria grows freely on any surface but the anaerobic bacteria responsible for COMPLETING the cycle needs more a specialized habitat.
Size a filter properly, set it up sensibly and you will have perfect water - it's that simple....and your filter won't be the dreaded 'Nitrate factory'.....you'll spend less money on treatments too......basically the filter is the foundation of a successful aquarium. 

This series of videos is all about trying to squeeze more efficiency out of internal and external aquarium filters which generally have a limited filtering capacity - If you have a filter you'd like me to feature in a video then please contact me on:
