While there may be some truth in what's said here I think following the instructions of the author for dosing practices is very poor. It's not a good idea to add something to the tank that you don't or can't test for. (While some trace test kits are available, fact is, just about nobody I know in the hobby have kits for the elements he's adding.) And, to suggest using your corals as an indicator is flat out scary. By the time a coral starts showing signs, it could be too late if the signs are bad.
The easiest and safest way to maintain all these trace elements in a proper proportional balance is frequent WC's with a high quality salt. In addition to my feeding regime outlined above, I would do 30g WC twice weekly on a 200g twv system with Salinity or Red Sea Coral Pro.
Remember that an addition of any element will impact it's ideal ratio and ionic balance within the tank relative to other elements. Elevated levels of "X" element will impact element "Y".
