I have looked literally everywhere and see none. I wondered to myself would a sump work without baffles. I know baffles are important so it can get through every single filtration but what if I have LR and skimmer on my sump and some mechanical filtration and probably add some bio balls along the way. Would that hypothetically work? Or would it just be not sufficient enough? I am new to sump and basically saltwater and just pondered upon this idea. I would love to hear all of y'all's opinion on this.
