The smell is anaerobic bacteria working in the bottom layer where no oxygen reaches. No amount of surface treatment will change that. Only moving the bottom water will.\u003c\/p\u003e\n\u003cp\u003eThe distinction that matters is bottom aeration against a surface fountain. A fountain looks impressive and does almost nothing for water quality, because it only ever touches the top layer that already has oxygen in it. A diffuser on the floor turns the whole column over.\u003c\/p\u003e\n\u003cp\u003eThe configurations differ in diffuser count and whether the compressor comes in a cabinet. The cabinet is worth having if the compressor will sit exposed; it is lockable, it damps the noise, then it keeps weather off a machine that runs continuously.\u003c\/p\u003e\n\u003cp\u003eTwo diffusers spread across a dam do far more than one diffuser working harder. Circulation is about coverage, not about making one spot bubble impressively.\u003c\/p\u003e\n\n\u003ch3\u003eWhy bottom aeration, not a surface fountain\u003c\/h3\u003e\n\u003cp\u003eStill water separates into layers.
