Re: FILYERING TAP WATER FOR FRESH WATER TANKS ?

Hi Robert

For a freshwater tank, if your using tap water, quality carbon
pre-filtration is sufficient.  RO is overkill, wasteful and expensive
for such usage.

You don't really need RO until you venture into a saltwater marine
tank.

If you decide to progress further, into a Reef Aquarium, RO is not
even clean enough, you should go with deionized water or better for
your salt mix and top-ups.

My second stage of filtration for Freshwater Aquaria is a silver
impregnated pressed carbon cylinder filter.  The first stage is just a
sediment filter to protect the pressed carbon filter from surface
clogging.  And even it is overkill for freshwater, but I use the same
source to feed my deionization columns for the reef aquaria.
