Microscopic View of Alfagrog

Alfagrog is a very rough knobbly ceramic filter media and is great for traditional koi filters where it sits in muck. As it is so knobbly fine muck will settle into the cavities and eventually support a good mic of bacteria and microorganisms - the less disturbed it is the better it works. It is a cheap way to fill shower filters but really only caters for aerobic activity (reduction in ammonia and nitrite) in that situation due to the lack of porosity and very aerated conditions.
When ammonia, nitrite AND nitrate is processed it is a full cycle.
Most filters and filter media only allow for half a job which results in high nitrates which have a long term debilitating effect on the fish .
The eyes don't lie and when you get a zoomed in view of filter media you can make your own decisions......why do no other channels show INSIDE filter media they (are often paid to) promote?
Because "trust the science".
Nope, trust what you see.

A guide to how much media to use for various stocking scenarios to achieve a FULL CYCLE can be found on the Q&A page of the FilterPro site: http://www.filterpro.co.uk as well as lots of other useful information.
Avoid using conditioners which bind / detoxify / remove ammonia, nitrite and nitrate as they prevent bacteria populations from thriving (by starving them). A normal water conditioner makes the water safe for life and allows the bacteria to achieve a full population in line with the available food.
