So it's becoming clear that my Phosphates and Nitrates will never get under control without some sort of nutrient export. So I am thinking of adding a HOB refugium to my 36g bow front. I like this one because the pump is not in the tank. Anyone ever tried this one? https://www.marinedepot.com/aquamaxx-hob-r-hang-on-back-refugium My question is do I keep mechanical filtration? And add this? Or get rid of my Aquaclear?
