Water changes & Temperature Fluctuations

Hey everyone

So now that my tank is cycled, i have another question before i add fish
regarding water temperature when changing water.

When i changed my water i filled my 20L jug with tap water (very cold)
I poured 2L of that into a kettle and boiled it and poured it back in to
raise the temp to closer to my tank temperature (but it was still a
little colder). I didn't get too worried with it being that i have no
fish, so needless to say, even with boiling some water the water in the
tank did drop in temperature by 4 degrees.

My question is, i need some formulas to figure out things like

"if i have 'a' litres of water @ 'x' degrees, and I add 'b' litres of
water @ 'y' degrees, then a+b = c litres at 'z' degrees."

OR

"if i have 'a' litres of water @ 'x' degress, how much water (b) at 'y'
degrees do i have to add to make a+b = z degrees."

I am sure i took some of this stuff in school some time, but damned if i
can remember any of it. Just one formula is good, i can re-work it to
find what i need (i remember that much! lol). Even a google search
term would be great.

Thanks

James

This link brought up nothing, but I did see Larry Blanchard's post from
less than a week ago! LOL, sorry I should have caught that before
posting. I canceled my post because there no responses yet, but after I
did that a response popped up... I am kinda new with newsgroups, so
perhaps I should not have done that.

This link brought up nothing,

Depending upon your browser, and my competence in posting, the second
line of that link may not have been included when you clicked. if you
get something like that in the future , a cut-and-paste of the full link
into your browser URL line will fix it.

but I did see Larry Blanchard's post
from less than a week ago!

The very post I was trying to link to :-)

LOL, sorry I should have caught that

NP. FYI, there is no "cancellling" a post in Usenet.

There are a few caveats to his advice. Read the rest of the thread
also.

Shouldn't that be "in" his advice? I'm not sure whether you're slagging him
off or defending him.

What he said was wrong, so i corrected him... usenet posts can be cancelled.

Although often ineffective, a message sent in error *should* be cancelled...
to say that it cannot be is to teach bad manners. We already have enough
goons on usenet - let's not train the puppies to **** on the carpet eh?

Read the rest of the thread also.

I did, before i replied, but that's of no consequence... a thousand lines of
wisdom may camoflauge a line of nonsense, but it doesn't stop it being
nonsense.

=======================
Then why not explain to us HOW to cancel them should we chose to do so?

Meh. You're right in that newsreaders have a "cancel message" command,
which will propagate across the newssevers. I've used it, but if the
message hits the Google Groups archive, or another web interface, before
the cancel command propagates, I don't see those sites pulling them from
their archive without further prompting (in the form of a direct
request/command sent to each web interface). So a sent message is as
good as "out there", due to Usenet's decentralized nature, and the
various web interfaces glomming off of it for web content at various
servers (which may or may not recognize your cancel command). You're
absolutely correct, though. A more correct reply might have been "good
luck canceling a Usenet post before someone replies".

=======================
Then why not explain to us HOW to cancel them should we chose to do
so?

From the menubar in Outlook Express: Message - Cancel message.

Most people set their newsreaders to poll every 5 minutes so, even if you're
quick, the chances are *someone* will have read it and maybe replied.

Some news servers don't accept cancel requests... but if you cancel a
message it'll stop most people from downloading the message if they haven't
already done so.

Cancelling a message the next day won't help much as everyone who's
subscribed to the group will have already received it, but it's still
courteous to do so if it was posted in error.

Hope that helps.
