Seawater... Buy Bottled Or Make It Yourself? (I Think That’s What This
Is About) – 07/24/07
Hi,
<<Hello>>
I hope this isn’t too
stupid of a question?
<<Only if you don’t ask>>
Am I better off
using 2-month cycled water with no nitrates or is R/O water mixed a day
before fine for a partial monthly water change?
<<Hmmm...not sure
what you mean by “cycled water” here...>>
I was thinking that R/O
would have to cycle a bit with a water change.
<<It is best to let it
“mature” (aerated/moved about with a power head) for a day or two before
use, yes...and if/when mixed with salt, to let all continue to mature
for another couple days or so>>
Is there any benefits either way?
<Maybe I’m being thick this morning, but I’m not real sure what you are
trying to ask here. Maybe this will help:
http://www.wetwebmedia.com/rofaqs.htm>>
My son likes to drive and buy
cycled water for a buck a gallon and I told him that premixed is fine?
Can you settle a disagreement?
<<Do you mean “premixed” seawater?
Best to do-it-yourself in my opinion...more economical in the long-term,
better quality control, etc.>>
Thanks Rick and Rick Jr.
<<Still
not sure I answered your question. EricR>>

Hi,
<<Hello again, Rick and Rick
Jr.>>
I guess what I am asking is my son likes to go buy water from
the LFS that is out of their 8,000 gallon reef for a buck a gallon for
partial water changes and I said and always have mixed my own with R/O
water.
<<Mmm, I see...so the store is selling their “discard” water
for other folks to use for their water changes...and darned expensive
too!. Though there is no real way to tell, this water will be lacking in
trace elements (have been utilized by the organisms in the reef) and may
even contain pest organisms. Cheaper and better to mix your own>>
The
LFS store’s water is perfect with 0 Nitrates and my son he likes to use
that because he thinks his tank might crash if he mixes his own.
<<Sounds like superstition to me>>
Could it?
<<Stands to reason
that it would not considering the majority of hobbyists and commercial
aquarium facilities use their own mixed saltwater every day>>
I have
always just premixed mine and did a 20 to 25 percent a month.
<<You
are in the vast majority>>
Can a tank crash if you do a big water
change with premixed R/O water.
<<A tank can “crash” for many
reasons, including doing too many/too big water changes...but not
because the change was done using R/O water and a properly prepared
quality salt mix>>
Thanks for settling this. Rick and Rick Jr
<<Hope this helps. EricR>>
Buying Water or Mix My Own?
I am very new to this hobby. My tank
is only 2 weeks old. I have been getting my water ready mixed from the
LFS. When I checked the spg, it was only 1.019.
<Fairly normal for
industry types.>
According to the FAQs I have been reading on your
very helpful site, this is way too low. Should I mix my own water to
bring it up and keep it up to 1.023?
<You probably should learn how
to mix your own water in case of emergencies (water changes after store
hours) and from the point of being cost effective. A S.G. of 1.020-1.027
is good depending on your animals (fish only, Red Sea fish, inverts,
etc). Take a look at http://www.wetwebmedia.com/spg_salinity.htm>
And
does this mean I should put new fish in the quarantine tank at the same
spg as from where I got it and slowly bring it up to the same as the
main tank?
<Yes, exactly. And you said you were just a beginner.>
Thanks in advance.
<You are welcome. Steven Pro>
