6 lines are known aggressors. The can work, but I have heard more horror than success stories with them. There are other wrasses that do the same pest control and are much nicer. Carpenter, fairy, melanarus, and a few others would work and be in the same price range. Firefish do well in pairs too, consider a second. You could also do 2 pistol shrimp with the watchmen goby if you like.
I also wouldn't have bleached the rock as the used rock has value in the microbes it holds more than the shape it is in. Since that ship has sailed, you can get some live rock from a club member to seed things with pods and bacteria.
I also agree with the idea of slowly adding the cleanup crew, or wait to add that much until you almost have an algae problem, so you don't starve your cleanup crew,
