Real quick question..... Tank Red Sea Max 250 AIO looking at buying something to break up flow instead of having flow in one constant direction. So my choices are a new Jebao SCP 70 for about $75 on Amazon or a used Maxspect xF250 for $80??? I am fairly certain I know the answer but just looking to confirm I am making the right decision. Or is it even needed in this tank eventually I want to get into having some really nice corals in the tank and could having the ability to have more flow be a bad thing ??
