Water change reuse?

G'day all,


I've been offered just about everything needed to start up a marine
tank.

Problem is, we have severe water restrictions here, and I like to
reuse the water I take from my tropical tank during weekly water
changes, and put it on my lemon tree.... the tree loves it.

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.

Cheers,


Ben.

Well, if you have a septic tank, it helps kill back the
tree roots growing into the drain lines.

You could plant you a mangrove tree :-) hehehe

Or how about a salt water pond :-)

I don't see why you couldn't put used salt water through a distiller
and reclaim almost all of it. I have not done this myself, but it
ought to work fine. You can get small countertop distillers from
Amazon for US$99 - US$200 that do a gallon at a time in four or five
hours. The question is whether it is worth the effort you'd put into
running a gallon at a time through the thing plus the cost of
electricity to run the thing. You'd probably want to clean the salt
and minerals left behind out between every gallon, too.

I have a countertop distiller that I salvaged from a chemistry lab, a
Kenmore something or other. It works great! I put a gallon of tap
water in with a pH of around 9.5 and I get perfect pH 7.0 water out,
and the inside gets coated in flaky red metal oxides that I have to
rinse out every so often. It eats about 300 watts, so for me it ends
up costing about 20 cents per gallon. I used to use distilled water
from this machine exclusively for my 25 gallon reef tank, but when I
got my 100 gallon tank it became unreasonable to try to make enough
water with the thing and I invested in an RO filter.

I'm curious now and maybe I'll go ahead and take some of the water from
my next change and put it through the distiller and see what I get.

Blake

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

Doubtful.

How would you 'clean' the salt and minerals?

What is the advantage of distilling your water from a water change versus
water from the tap? You will NOT be able to separate the crap from your
salt and minerals for reuse.

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.

Because you don't have live coral.

'He' is doing water changes because 'I' don't have live coral? Very
strange.

Maybe he doesn't want them dude!
BTW, there is a method to avoid water changes for more than twice a year is
any at all.
Since you are an expert on the matter, you should know, lol

Reef keepers that know what they are doing, do water changes.

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

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.

The question is whether it is worth the effort you'd put into
running a gallon at a time through the thing plus the cost of
electricity to run the thing.

Doubtful.

I agree that in most situations the cost of electricity to run such an
apparatus is going to be much greater than the cost of tap water + RO
filtration. However, the original poster had said they were in a
situation were there were restrictions on water consumption, thus it
might be worth while to use electricity, which might be in greater
supply, to reclaim the water.

You'd probably want to clean the salt
and minerals left behind out between every gallon, too.

How would you 'clean' the salt and minerals?

Sorry, what I should have said was, "You'd probably want to remove the
salt and minerals left behind in the evaporation chamber between uses."
If you'll recall from mixing salt water for use in a marine
environment it takes about one half cup of salt mix per US gallon of
pure water to make salt water, so after you've distilled that water
you'll have about half a cup of salt left over that you'd probably want
to clean out before putting the next gallon of salt water into the
chamber.

my next change and put it through the distiller and see what I get.

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

Lastly, why are you doing water changes to begin with? I don't do water

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

Blake.
