Brita Filtered Water

[CrustyOnEastCoast]

For our home drinking water, we use a Brita Filter. This filter is an "activated carbon and ion exchange resin" filter that is certified to reduce:

Copper
Mercury
Cadmium

It also reduces chlorine (taste and odor).
It doesn't eliminate flouride (which we have in our tap water).
Also, "The Brita Filter is not intended to purify water".

If I test this water I still get the 1.5ppm Ammonia reading that I get testing water directly from the tap (but I think that is picking up the chloramines).

I was just wondering if I should use this filtered water for my fish tank along with a dechlorinator, of course). Brita have a FAQ on their web site about this very question, but they refuse to answer it.

I thought about the same thing, then I thought about how long it'd take to filter at least 30litres of water and quickly decided against it lol

Yeah It sounds pretty expensive to use if you run a big tank and run a few water changes a week. I just use straight tap water.

I think it would not be worth the effort. Your cycled filter will do the job you need as long as you add dechlorinated tap water.

I also have brita filtered water, but I read on there website they dont recommend it for tropical fish.

This came up a few weeks ago, so I took the opportunity to test the filtered water. Compared with my plain tapwater, it lowered both the GH and KH, and the pH dropped off the bottom of the API liquid test kit, so it was less than 6.0.
