Greater Spotted Woodpecker creating a nest hole in a tree in my garden. Storms broke the top of the tree off a few years ago but instead of felling it, I left it for the woodpeckers feed from. Now that it is easier digging, they are making a nest hole which is in view of my kitchen window. Nice. ... https://www.youtube.com/watch?v=mllpUg5bKNI

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 worlk bottom to top) Eheim Substrat Pro: https://geni.us/98euQaB (decent alternative to Biogravel). This is a well made filter which has a surprising lack of space in the trays due to the strange shape of the filter body / trays. Nevertheless it will easily hold 2kg (4.4 lbs) of Biohome Ultimate making it suitable for a normally stocked tank of up to 200 litres (52 US gallons) or a heavily stocked tank of up to 100 litres (26 US gallons) for a full natural cycle. 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.........
