From time to time i use carbon, or a phosphate sponge, but thats really it...my sump is basically bare....I do however have 3 drip trays which all have different filter pads embedded in them to take out the unwanted from the tank...

Are you talking about a refugium or sump? A sump should just have equipment such as heater, skimmer, grounding probe. A refugium is where you put LS,chaeto..etc. Some people do section a portion of their sump as a refugium, but it should be a separate tank with low flow to be efficient.
