Sidelight: Microdyne is not iodine, it is not iodine based, and it is not good at killing pathogenic bacteria.

Microdyne is actually colloidal silver, which has only low kill rates (40% - 60%) on some kinds of bacteria, and Microdyne has zero effect on some key pathogens like Salmonella, especially typhoid. Also note that the US FDA and US NIH have published warnings since 1998 that colloidal silver - like Microdyne and Bacdyne et al - do not work.
The advice about bleach for reliable disinfection of drinking water is spot-on accurate.
For Corey's situation, it's also worth noting that Yucatan peninsula can have such hard water, also with elevated salinity in coastal areas, that many people find it not palatable for drinking even when filtered and UV treated.
What is your water supply?
If it is a municipal water supply using deep wells, their chlorine treatment may be enough to ensure safe drinking water at your water meter. For example, Merida's city's water at the 97% of meters is very clean. When scientists tested the same addresses, but checked water quality at the kitchen sink, roughly 25% of the homes had fecal coliform contamination in their home tinacos and home plumbing, even though the city water supply was clean.
This means that a whole-house water treatment system installed where the water enters the home, would not kill contamination from inside the home's plumbing. This is one reason some people opt for treatment at the sink, or buy garafons of purified water.
Also note that a whole house water treatment system likely removes chlorine, which means the treated water has no residual disinfection. This also means that for that 25% of Yucatecan homes with contaminated internal plumbing, no residual chlorine in the water can mean no residual disinfection protection against in-home problems.
