Thanks Mr. Lizard.
I understand what you mean about the replacing lost trace elements and calcium when needed. I thought about that as I was writing, but just got a little lazy and didn't include it.
Some of these theories and proven practices (Boyd) are my plan for when I get my 55 up and running again. I will; however, be implementing a skimmer for when/if the natural way does not work to keep up. It is a work in progress with no time limit. I am not in a big hurry this time.
Thanks for the information.
