How do you supplement calcium?

[BCOrchidGuy]

I've used Liquid Reactor, I've used Purple up, I've used Turbo Calcium, I've used SeaChem Reef Calcium etc.. all with fair to good results. Now I'm going to try the RFH two part method, I just picked up my Dow Flake and Espom Salts today. If anyone does want to try the RFH stuff, Dow Flake is available at PK Building Supplies in Surrey, not sure of address but they are on 88th and the corner of 189th. A 20Kg bag of Dow Flake was $33 including tax.
