Interpet PF filter range: https://geni.us/EK5Kod At the time of making this video the filter was on offer at £21.95 with free delivery - that is a great deal and even if you don't need a new filter this will make a great back-up for your existing system. Filter Kits, Foams, Biohome, Biogravel etc: http://www.filterpro.co.uk (FilterPro site has links to Biohome suppliers in other countries) Eheim Mech: https://geni.us/lXrB7 (useful for under trays in filters which work bottom to top) Eheim Substrat Pro: https://geni.us/98euQaB (decent alternative to Biogravel). This is a well made filter which has a decent amount of space inside and even if you choose not to upgrade the filter it is great value. *Avoid using water conditioners which claim to bind / remove / detoxify ammonia, nitrite and nitrate as it will have a pronounced starving effect on the bacteria. When bacteria is starved the population will be low as it grows in line with the available 'food'. A normal conditioner will allow the bacteria to fully populate the whole system and take away the 'need' to add more bacteria after maintenance / water change. Most people get conned into regularly using bacteria additives and that is simply to mask the side effects from a damaging conditioner and a failing filter. A normal conditioner like Tapsafe, Aquasafe, API Stress Coat etc. is all you need when a tank is properly set up, a filter is suitably sized (and properly set up) and Nature is allowed to so what Nature does.* See below for notes on how much media is recommended for different stocking scenarios. The Q&A page of the FilterPro site has extensive notes on recommended treatments and how filtration works.

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 filter media 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. Remember to use a water conditioner which does not bind / detoxify ammonia, nitrite or nitrate as that type of conditioner will severely limit bacteria numbers by starving the bacteria of 'food'. 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 We all are on a long path of learning.........
