Plumbing shopping list?

[rishu_pepper]

Thanks for all the advice so far, it's starting to make sense to me.

Mindy, I bought a DCT12000, which is handy because it has controllable rate of return. The tank is 165g and the sump 50g, and head is maybe 4'~ vertical? I figure the DCT12000 has plenty and more flow than I'll need, so I can always dial it down.

What is the advantage of running a manifold? How hard/easy is it to install it?
