As title asking $450 for the set. Pick up in Brooklyn or Staten Island.
you will need to purchase the adapter cables:

fill a compartment with water and see if it leaks to other compartment without going through the baffle, but internal leak doesn't really matter as the water is all shared anyway, so an internal leak doesn't really need fixing.
take things slow, I know that feeling of wanting to buy all the colorful corals and stuff, but patience is key in this hobby. Just stick to regular wc, adding things slowly, and use coral dips.
As title states, frags are so overgrown on the rack and I don't have the proper tools (small chisel and hammer) to get them unstuck.
So selling them all as a package, yes, including the rack.
Looking for $150 picked up in Staten Island or Brooklyn.
