It works, I have it in <"one filter"< (Eheim 2224). I just 3/4 filled the media basket.Has anyone tried K1 micro media in fluval external filters? If so how does it perform?
<"It was">, but it will develop a biofilm in an external filter.It is designed as a floating moving bed media.
If some-one else is buying I'll have "Eheim Substrat Pro", but I've use floating cell media, Alfagrog and Hydroleca etc without any problem.In closed system you should use something porous like lava or biohome pellets etc..
