Hey another question! I recently bought a 240gph wave pump made by koralia. The employee at the local fish store said it would be a good idea to put in my tank. It is a 20G tank and it already gets a fair amount of flow from the filter pump. How do I know if i really need to put this into my tank? And if so where do I put it? would my Bubble tip anemone get stuck inside it? (I've heard bad stories)
