Hello people! I'm here to ask if any of you have experience with the filter media that the youtube guy, pondguru, from tyne valley aquatics, sells on ebay. he sells a lot of different types of media, and he claims that biohome ultra is the best media you can get in the world because over time it can sustain anaerobic bacteria that consume nitrates, not only aerobic bacteria, that consumes nitrite and amonia. If any of you has any experience with this please share it with me, I might order some for myself! and if you don't know it, you might just give it a look! looks very very interesting!
