Water change reuse?

BTW, there is a method to avoid water changes for more than twice a year
is
any at all.

Can you explain how? I have to do a water change at lest overother month,
might be the amount of fish I have in the tank.
Thanks Steve

I don't see why you couldn't put used salt water through a distiller
and reclaim almost all of it.

Why would you want to do this? What are the benefits?

Well, you see when you distill water you separate the pure water from
all other dissolved minerals. You can take salt water and distill it
and what you get is pure water and a pile of salt and other minerals.
You do this by boiling the water off and then condensing it somewhere
else. When you boil the water the vapor that is formed only contains
H2O, everything else is left behind.

It is possible that aquarium water contains low boiling trace organics that
would also distill over, I'm not sure.

He would be better off collecting rain water and distilling it.

Again, the goal here is to conserve water. I am not sure there was
also any incentive to reuse the salt.

How would you reuse the salt?
It would be next to impossible to separate the water soluble organic crap
from the salt.


Lastly, why are you doing water changes to begin with? I don't do water
changes and my fish, inverts and live rock are doing fine.

That's very good for you, congratulations. However, I believe the this
subject is probably beyond the scope of this discussion.

Au contraire! This subject is the very answer to his problem. No water
changes = ultimate water conservation.

I suppose it is possible. If there were any ammonia in the tank I
guess that might boil off first. Technically, though, anything with a
lower boiling point would boil off first at whatever temperature these
trace organics boil at, then there would be a period where nothing
boils off as the mixture heats up (all energy injected to the system
while anything is boiling would go towards the phase transition and not
temperature change) and nothing boils off. Therefore, you could just
discard anything that the distiller produces before the chamber reaches
100 deg C. Of course, that is even more complicated.

Assuming that there is enough rain. I think there tends to be a
correlation between areas on the planet that don't have much rain and
areas where water consumption is restricted.

from the salt.

I don't know. I did not mean to suggest that the salt would be
reusable. I was thinking of this as an exercise in water conservation.
If you don't have access to water, but you do have access to things
like electricity and salt mix, and you're somehow in this situation
where you need to have fresh water in order to keep your exotic marine
animals alive, distillation is probably the answer.

On the other hand, I'm sure there are ways to separate the bad organics
from the good minerals and reuse your salt mix as well, but it would
probably require a pretty sophisticated chem lab and maybe a few grad
students.

changes = ultimate water conservation.

That's true, though I think such a discussion might be better placed
under a topic with the title "Amazing No Water Change Method of Reef
Keeping." Or maybe, "Water Changes: Who Needs Them?" Or even, "Pros
and Cons of Water Changes."

If I explained how I'll get bombarded AGAIN with insults by retailers that
want to sell!
I had not have a water change for a year now, it is a FWLR system ready to
be upgraded to a reef as soon as I find a good lighting system ( I am
looking into a T5).
My tank is a 65gal tank, 20gal refugium with 30 inches of livestock (add up
the length of your fish and invertebrates as a rule of thumb for an inch of
fish you need a gallon of water)
Is as easy as IN-LINE filtering. When 100% of the water goes throw the
filtering system in different phases (my filter has 7 phases that mimics the
natural environment), all the water gets treated and it returns recycled to
your tank.
Calculate the total length of your livestock and compare it to the volume of
water in your aquarium minus all the volume displaced by rock and deco.
You see, retailers like Wayne won't tell you this because they loose profit
or they just don't know. After more than 20 years as a coastal marine
biologist I designed a filtering system that does just that.
When I came here with the idea a year ago, everyone laughed and insulted me.
Now after a year of experimentation, I HAVEN'T HAD ONE SINGLE WATER CHANGE.
Am I selling my filter yet? no, still waiting for it to be patented but any
book on Marine Biology will give you the idea.

Distilling water is not such a good idea. I used distilled water in my tank
for two months and my KH dropped like crazy. See, distilled water has no
KH.
To tell you the truth, I save tap water and sit it for a week. My filter
takes care of stabilizing it but I keep the new addition to no more than a
gallon every two weeks.
Remember, I don't have a reef aquarium, corals are very sensitive to
chlorine, even a small amount will stress the polyps not to mention
anemones.

What about phosphates? My tap water has about 5 ppm.

Remember, though. The OP was about what to do with _used_ water changes
taken out of the aquarium, in an effort to conserve water;

"Is there anything I could do with water change water from a marine
setup... or is it a case of tip it down the sink.(?)"

Presumably, the OP will be getting his original mix water from a source
that he finds to be acceptable, and is looking for a way to make salt water
useful after it has served its function in the aquarium.

I'm with Frank, keep the used marine water in a bucket by the loo, and use
it to flush the toilets, in place of city/well water.

Most people do a 15% water change once a month. I like
doing a 50% water change about once every 3 to 6 months.

Here in the store, I use RO waist water for the toilet. It
goes into the back of the toilet. And when you flush,
normaly the water in the reserve goes in the bowl, and as
it is filling the reserve, it also fills the bowl with the
smaller tube, But I moved the smaller tube so that it
fills the reserve instead, and the ro waist water slowly
fills the bowl. One nice thing about that is that if there
is backup in the flush, it won't spill onto the floor.
