This is about a 4 year old thread.
To answer your specific question, you are adding a bunch of stuff to your reef and you don't even know what's in it.
One thing you'll find out very quickly is that there are no "miracle" cure all products, especially when it comes to adjusting pH in SW. Yes, you might get the pH correct, but doing it with such a "shot gun" approach tends to get something else, just as critical, out of balance.
While I'm on a rant, take one of those printed catalogues from the "big time online stores" and go through it. Put an X over every product that is out and out junk, substandard, or otherwise just shouldn't be used in a reef system. It's amazing how much stuff you'll find.
