I am new to the hobby and beginning to feel overwhelmed with the amount of options available to hobbyists and which options are the best route. I have a 75 gallon reef ready tank that came with no plumbing setup. I was going to do a herbie dual drain with an over the back return but now I am seeing that its better to make a manifold, for whatever they are used for, to make attaching different things easier. Some setups I have looked at have pipes attached to the manifold that drain into different sections of the sump completely bypassing the filtration system. My question is what is the purpose of a manifold, do I need it, why do some people use it to skip the first level of filtration.
