I have had my tank set up for about 5 months now and when i first started my penguin 330 filters rocked. The bio wheels were spinning fast and you could tell they were moving a ton of water. Now the bio wheels go very slow, the slowest i have seen ever and the water coming out is just an ok amount now. Have any of you had this problem? Solve it? Should i just go buy a different filter? What kind? Emp 400? I have heard great things about these. thanks
