On another thread, I learned that I am a bit behind the times on the treatment of water and on water filters so I thought I would post this... First, I need a good water filter that can move water from a 55 gallon (BPA free) drum (purchasing 2 of them) reasonably quick for family use - meaning - I would be needing 2+ gallons at time so I don't want a Life Straw type filter. I wonder if anyone has recommendations concerning this and why would you recommend this. Secondly, I wonder if there is some way to treat the entire 55 gallons prior to use so it does not have to be filtered? Is there anything out there now that is trustworthy to kill everything but doesn't leave a bad taste? Third, I have used a LifeStraw in the past. And, was considering purchasing some but thought I would ask the Tree if there is anything better now available?
