What size of UV filter would be appropriate for a 10-gallon FOWLR tank that uses ordinary tap water? Non-RODI water usually creates algae and I want to know how big of a UV filter will eliminate the algae.
What size of UV filter for non-RODI water?

I wouldn't use ordinary tap water unless it's a freshwater tank... Algae is pretty much par for the course in any thriving reef tank, and you're more likely to have other issues if you don't use RODI for mixing.

Do you know where I can get an inexpensive RODI that I can connect/disconnect to a garden hose? I have a 20-gallon Brute mixing bin where I prepare the saltwater and it is next to a garden hose.

There is no sink next to my saltwater prep container as it is in the garage next to the garden hose.

Are you referring to this: ?
And what does it mean by "50 gallons"? And how do I connect this to a garden hose?

Mine is a bit different, but that's a popular one - yes. 50 gallons per day of RODI water. You'll probably need an adapter at your local Home Depot (etc.) but it does come with some of the plumbing fittings.

"The RO Buddie+DI will produce about 2 gallons of filtered water per hour if your water pressure is 65 PSI and the water temperature is 77°F." Does this mean that the water coming out is very slow? Is there any way to make the water come out at normal speed?
I would pass on UV for algae control. It only works on particles in the water column. I ran 2 in the past and they did absolutely nothing for gha, cyano or diatoms. I didn't expect them to but many people think they do when they read they kill algae. To be honest I'm not sure what types algae they are supposed to kill. 
Not really because it still typical slow RO rate going into the tank. The pressure tank just increases the flow out of the tank and are normally used for drinking water systems to push it out of the faucet. They will not speed up the RO process. A booster pump can help with that if input pressure is low.
To the OP is buying RODI from a lfs an option? Not my recommendation but would probably be a better option than using tap.
IMO, Too many issues that tap water will cause that make a UV filter well down the list of priorities. I would use the money to help save for an RODI.
Another option is to by water from the grocery store since you can do a 10% water change with 1 gallon of it.

Get an RODI unit, there is no excuse not to. There is no earthly thread pitch/count that you cant convert to/from. Yes you can hook them up to a garden hose with an adapter for that thread pitch/count, yes you can hook them up to a faucet, yes you can hard plumb them. Hell, I even have a contingency plan to filter collected rain water through my RO unit if SHTF...
UV does not remove any other contaminants from water such as heavy metals, salts, chlorine or man-made substances like petroleum products or pharmaceuticals.
The way the RODI process works requires pressure and time, just like reef keeping, if you cant handle either (or both) there are plenty of other hobbies that cost a lot less for the same punishment.
