Some more reading tonight, and found a list of causes! Geez...it's like being doomed in a way.

Other Potential Causes
Besides the water quality deterioration or bad condition of it, there are other other causes that can lead to the onset of bacterial infections. The main ones are related to damage that occurred to a coral, the damaged area gets infected and bacterial disease follows.

Here are some of the reasons:

An urchin, while crawling through the tank, inflicts a scar or puncture to a coral
Sweeper tentacles from other nearby corals can sting a coral and leave a puncture of damaged area behind.
A piece of rock falls on a coral and causes a puncture or damage.
Bristle worms gnaw at a coral and cause damage.
A mantis shrimp with its razor sharp front mandibules causes damage when it touches a coral or brushes it while roaming around the aquarium
A fish causes damage in the process of touching a coral, possibly through sharp gill end, or in the case of Tangs, the brushing of their back razor sharp protective modified partial fin against the coral.
Any fish that eats polyps damages a coral (e.g. Angel and Butterfly fish - I include Pygmy Angels in this category by the way as some will harass corals and may damage them in the process).
Hermit Crabs can cause damage.
Small algae eating crabs can do the same, inadvertently but with the same end result.
Stone crabs moving around and touching corals or rubbing their claws against them, even if not on purpose.
Some shrimp may do the same, even inadvertenly.
Some nudibranchs (most are carnivorous) feed on corals or leave toxic excretions behind.
Detritus that accumulates on corals, rots and is not removed by current will eventually damage the polyp of a coral to the point where the damaged part can easily become infected.
Some sea slugs
Wrasse that are not reef compatible present in the aquarium. In this respect it is very important for hobbyists to ensure that whatever they add to their tank, is compatible with what is already in the aquarium. This applies to any type of animal you add not just corals and fishes.
Some snails that get onto the coral leave toxins behind as they crawl along. These toxins may harm the polyp. The secretions left on the polyp may, in fact, harm the coral and cause damage.
Small worms that attach to corals (usually white and round type worms). They are hard to eradicate and multiply rapidly. Another document will be added to the Main Library to deal with the eradication of these worms. In brief though, irritants have to be used so they detach and can be siphoned out. Some fish eat them. Six-Line wrasse are a good fish to try out.
Algae that touch corals can, while excreting toxins and general excretions, damage a coral.
and so on. This is a pretty good overview and you should have gotten the picture from this list how easily, indeed, damage to a coral can occur.
Remember that "any" damage can develop into bacterial disease.

The rest of the article on http://www.athiel.com/lib/bacterial.html deals with some of the ways to cure it. Vitamin C no less. It's 3am here, and I'm tempted to go view the tank in the dark to see if I can spot those crabs that might be causing some of my issues. Coral eating...going down the toilet bowl crab! I wonder if I have more than one. We really haven't gotten anything new, so he's been there for a while. Those crabs eat fish too!! We lost our scooter blenny just recently, along with the damage I am almost positive he did to my brittle star!! Ack...gotta sleep!
