Not-frequent water changes...

[Pszemol]

How often and how much water do you change?
Have you experiment with not changing water?
What systems were they and how were they doing
without periodical water change?

I dont change water regularly on my breeding tanks cant afford the $40 a week change, plus
it takes the better part of 2 days

i test my reefs every other week and change some water if nitrates/phosphates are
elevated. ive gone about 4 months between changes. my single LPS is lacking, but my SPS
and softies all grow like mad.

my preditor tank gets 10g changes every week its a 75 in desperate need for an upgrade.

I don't like doing water changes, and in the past I wouldn't do them for months
at a time. As long as the tank was healthy and the parameters were good, why
change the water?

Now I'm doing them once a month. 10g changed in each tank (2 x 29g, one 55g).
I do the change on all three in one night, to get it over with. :)

Most people do a 10 to 15% water change every month.

I like doing a 50% water change every 3 to 6 months.

It's best if you can, especialy if you are going to make 50% water changes, to
make the water well in advanced so that it hase time for the chemicals in the
salt to react with each other. The easyest thing to do is to just make more
salt water after you get done making you water change, then the next time you
want to make a water change, the salt water is already made.

I am a big fan of water changes. I do 10gallons on my 75 every 2 weeks.

Water changes can be so expensive. What about doing a water change, keep the
old water in an open container to evaporate the water and retain the salt
and then add fresh water to the container? I would think in time the
nitrates would disappear, and adding new water would add new trace elements
to the water which you are basically trying to accomplish anyway. In other
words recycle the sand.

bad move, many reasons search on using sea salt if your inclined.

sure

no it wouldnt. at least not real "trace elements" only those thigns sold on a shelf that
you dont need for your reef to begin with.

if your more inclined to skip changes then look for either inline filtration or external
filtration both work very well, both serve different purposes. a Large refugium with lots
of light and algae compared to tank size will do along with several different filtration
systems geared at lowering/removing nitrate and phosphate and such.

Very interesting idea. I never have done it nor how to. Can you try it and
tell us those step(s) how you accomplish it. If your idea and step(s) work
and doable. I would like to adopt your concept.

I have heard that in the process of drying sea water there are
some irreversible reactions which make dissolving difficult
or in other words: after drying sea water, what you will get
with dilution is not exactly sea water...

Other experience I tried myself was to try to dissolve salt mix
with small amount of water, kind of wetting it. I just measured
salt and put it in the container where the RO water was dripping.
I got salt slurry and after that, even adding enough water I could
not get all salt to solution - had white precipitate which could
not dissolve... After that experience I always try to add salt to
water, not the other way around, so wet-salt sounds kind of crazy...

Why did you change your approach??

I thought I would err on the side of caution for a while. :)
