Yes, Its my turn to go bigger on a sump...I am going to design it with baffles as I have a AquaC Remora overhang skimmer and just cant seem to eliminate the micro bubbles and sediment I seem to have developed. I believe it all stems from when I added a gallon size ziplock bag of very fine figi live sand to boost my organics in my tank. The substrate in my tank is a hawiian medium coarse sand with like black volcanic larger particles. For whatever reason, I felt I wanted to add finer live sand. I did. But, I think that is what has contributed to my sediment. The micro bubbles,....well, with the overhanging skimmer it has quite a drop into my sump. And with the benefits of going bigger on the sump. The water quality shall be easier to maintain. I am purchasing a used 40 gallon tank for the sump. I can then add baffles and such. Any ideas will be apprecited.
