I have an aqua tech HOB and it was slowing way down after 5 months, I rinsed it off with each water change in the water in the bucket, but I noticed a real slow down. I put a new one in today, but..... what do I do with the old one? there is no room in my HOB for the old filter, as there is a second filtration in it. Sort of a hard mesh kind of thing. will these be enough bio so I can throw the old filter away? There is just no room in the filter bo for the old filter.
thanks I await replys
