I just wanted to share what I have learned from what I experienced with my wet/dry filter. I have two overflows in my 120gal going to my sump. I had so much trouble with micro bubbles and people on here told me to cut back on the pump power. Well, I have two pretty powerful pumps going; thankfully I thought beforehand and put valves on each return. I ended up shutting the valves more than half which actually improved the entire function of my system. Here is what it did for me. It all but stopped the micro bubbles and it also is cleaning my tank better. Before, I was changing my filter material twice a week because the intake was literally blowing holes in the material. There would be so much dirt in the bottom of the sump that I had to empty and clean it every week or two. Now, the filter is collecting so much filth, I clean it nearly daily, no holes in the material now, and no more dirt is collecting in the bottom of the sump! Just my experience with how it really doesnââ"šÂ¬Ã¢"žÂ¢t matter how much volume you push through your filter, you need to make sure it has the chance to do the job it is supposed to do, which is to filter what water you do have going through. I am new to all of this, so I am only sharing what I am experiencing.
