What should i buy to purify my water?

[scherzo]

Here is something interesting but also something that I suspected.

Chilliwack gets its water from an aquifer (ground water). It is much more susceptible to contamination (from what I have heard.. I am not an expert).

Have you checked your source for nitrate or phosphates? (right out of the tap)

I forgot to say.. I have a Lawnmower Blenny that keeps my green algaes in check.
