Re: FILYERING TAP WATER FOR FRESH WATER TANKS ?

Hi Dan

You are correct in that regard!

In some areas of the country, namely those with hard water, a minor
plumbing leak is only a temporary nusance that will often heal itself,
keeping those things you don't want clogged clean, like aerators and
showerheads is another matter.
In the areas with soft water, or artificially softened water, leaks in
piping is commonplace and must be dealt with quickly, before it soon
becomes an unwanted flood.

But our true topic was in reference to aquaria and its water
properties.
You want to place as few contaminants as possible into an aquarium!
A freshwater aquarium will naturally go acidic and hard water is
beneficial in this regard.  Thus my reason for saying, any filtration
beyond pressed carbon is overkill, as you are removing the things you
technically need in a freshwater aquarium.

However, in saltwater aquaria, namely reefs, you want to control the
additives as closely as possible and keep out as many of the
contaminants as possible.  Yet there is even overkill here too, you
don't need triple distilled water from an all glass Barnstead still to
properly maintain a reef aquarium.  A good quality salt mix adds those
nutrients that should be introduced into the aquarium at the time of a
water change.  Thus the purer your make-up water, the closer to
correct the resultant make-up solution will be.
