When a pump is air locked, there's NO water flowing through it. You have water flowing. Hence, no air lock.

"Im hoping the shells do because they can be exposed to long periods of sunshine"

This is not correct. Most manufacturers will NOT cover damage caused by leaving the cover off for extended periods of time and damage to the shell caused by sunlight.

In Topic: Selecting The Best Hot Tub For Water Sanitation

Every other spa, including lower level hot springs only filter 25% of the water at one time regardless of the size of the filter.

Not quite true. The original design of a single filter, with bypass, is such that when in heating and/or filtration mode (pump on low speed), nearly 100% of the water is being filtered. This is the majority of the time most pumps operate. When the user is then in the spa, and turns on the pump for the high speed action of the jets, then much of the water bypasses the filter. First, there's no real reason to need to filter the water during this short period of time. Second, it would take a MUCH larger pump to move the same amount of water through the filter, with the pump on high speed. Third, with %100 filtration, as the filter get dirtier, the pressure at the jets becomes less and less. This "value" equates to a more expensive spa, with a nice sales pitch.

Can I convert this to a 220 w/o running a new wire?

Maybe. It depends if you have 220 running to the panel at the pool. If so, and there's room for a double pole breaker, then yes, but you'd have to run and additional wire from the pool panel to the pump. Of course, you may already have 220v at the pump. No offense, but if you're already unsure about this, you really should consult an electrician on site (I suspect your "two 30amp breakers coming in from the main to the pool" is actually a single, double pole 220v breaker).
