I am also in a situation where I could not set up a permanently attached RO/DI unit. I got a three stage Spectrapure system and changed out the fittings on the intake line so that I can just screw it onto the bathroom sink faucet, like a garden hose. One day a week I run enough water to last till the next week. I just sit the jugs and/or buckets in the tub, next to the sink, and let the waste water run down the tub drain.
Not having it permanently set up is a bit of a pain, but it is worth it for better water. The water in your tank can never be of higher quality than the water you start with.
For what it is worth, even with the good water, I still get occassional algae blooms but they are not as severe and by catching them when they start I can overcome them much more quickly. I'm still pursuing the goal of eliminating the blooms altogether. I doubt that is a possibility, but it is a goal to approximate.
