It looks like the Rena Filstar XP2 is no longer in production and the few XP3 filters I found online were crazy prices. If you can pick one up second hand at a good price then go for it.

The set up of this filter will also apply to the XP3 and XP4 as the same method applies to all the filters in the range (with varying amounts of media required).

WHAT IS A FULL CYCLE?
*If someone tells you the aquarium nitrogen cycle ends with the production of nitrate that is incorrect - please read on*
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'.

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:

Anyone who sends a filter (UK only at present) will have it upgraded and returned to them for free and the only cost you will pay is how much it costs to ship it to me - I'm helping to boost your filter and the resulting videos will hopefully be useful to viewers all over the world so it's a win/win. 

The following videos will be useful to anyone interested in learning more about filtration, bacteria and making the conditions for your fish as good as possible:
