Well that was my experience the very first time i used it. I filtered out of the same stream, exact spot even. The first time i used it is tasted good and clean, i than filtered a liter and treated it just to see what that tasted like.

My second one was a week later and just has this odd taste to it, like its just dirty water. Thats when i read on here about cleaning the filter with bleach, but i wouldnt think it would need done after just a week would it?

As i said im new to filtering water, so any advice on this id like as i did a lot of reading on the squeeze before i bought it, and i really like its simplicity.
