interpet pf filters
im not really a fan of these as it seems they performance drops each day. the flow just seems so weak on my pf4 the biggest one thats like £45 to buy. compared to the fluval u4 there's a big difference yeah my fluval u4 is going for weeks and still performing well. I just wonder if the pf filters are prone to this poor flow after a while? I mean I give it a clean in old tank water on the parts and media but it seems to get worse everyday lol I never had an internal filter like this.
