Dennerle Scaper's Flow: http://geni.us/LUcx Cheap mesh media bags (small): http://geni.us/DtoexHC Foams and Biohome Ultimate: http://www.filterpro.co.uk (FilterPro site has links to suppliers in other countries) The Dennerle scaper's flow HOB / canister filter is a really interesting design which offers a decent provision for both mechanical and biological filtration. Trays are really easy to set up with alternative media / foams and they fit together very securely to eliminate bypass. The top media tray holds around 550g of Biogravel so is really suited to normally stocked tanks of around 60 litres (16 US gallons) or heavily stocked tanks of around 30 litres (8 US gallons) if you want to achieve a full cycle. If you are using this on a well planted tank you could achieve a full cycle in 100 litres+ 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: sales@filterpro.co.uk 07772848730 (Richard) Anyone who sends a filter (UK only at present) will have it upgraded and returned to them for f ... https://www.youtube.com/watch?v=GL4v91YOwQE
