For your phosphate reactor, take a look at the ViaAqua Poly-Reactor. I bought one and it's pretty much a plug-n-play unit. It comes complete.
As for the calcium reactor, Whoever you buy from, I would call and see if they have the package that includes the PH monitor/controller lid. You shouldn't have to buy a new lid just to complete your system.
