Danny, keep in mind that a 2-part will replace you Alk supplement scheme with something 40 times more expensive. If you're good with your washing soda mix, then look for Turbo Calcium online (J&L).

To start buying a 2-part liquid now will pay for a reactor in about a year.

Another decent Ca liquid is Seachem Reef Complete, though it doesn't give the results people are reporting from Liquid Reactor. And to get it MO is about half the local price.
