Title: 2 Ounces is weight or volume?
Post by: TubbinSoon, now we be tubbin on February 07, 2005, 02:45:30 pm
I keep seeing references to 1/2 oz or 2 ozs and wonder if granular dichlor is measured by weight or volume or are they close to same for some chemicals?

I'm going out on a limb here, and guessing it's volume.  

With the sanitizer regimens I've done (Baqa first, then Brilliance), both use the same graduated scoop for measuring chemicals.  But the chemicals all wouldn't have the same density.

This leads me to believe that it's volume.  That would seem like a clunky way of measuring.

Ounces is a measurement of volume (liquid). As many chemicals vary greatly in concentrations, it's difficult to recommend a generic amount for any one chemical. Often, dealers work out a quantity based on their brands and given product. Not too many of us have scales sitting beside our tubs to measure grams(other than salesdvl that uses his for alternate reasons ;) ) so rather than give a measurement of weight, often we suggest a recommended dosage for dry chemicals based on ounces which is easier.

Ok,

so who has a table that converts all of this to tea and table you know whats?

Does anyone really measure ounces or volume. I thought a sprinkle of this or that was proper? ???

Jonathan,

If you have a Taylor kit - it's in the book.

If not I will look it up for you.

Again, it entirely depends on the concentration of a given product. I don't know of any one table that can produce an accurate conversion for the wide range of products available.

Alrightie it looks like the answer is volume.

But the LeisureTime granular dichlor is dry what, 55%? So is the true anwer just to shake some into a vessel, shake it up until dissolved, pour into tub?

(digressing into torque measurements, tight enough but don't wring it off and when you wring it off, too much? My arm is calibrated but I still broke the strap wrench trying to loosen the 2" PVC union last night)

3 TSP = 1 TBLSPN

2 TBLSPN = 1 OZ

3 TSP = 1 TBLSPN

2 TBLSPN = 1 OZ

Which side of the equations is the wet or dry side? Is 2 TBL dry = 1 oz liquid? I think this is what you are saying.

This is a great tool!
thx

Yup.  Two tablespns = 1 fluid oz.

Actually I started working on a chart for this some time ago........ started..... here's what I gotts so far;

1 ounce, dry weight,  equals =

Sodium dichlor (chlorine) - 6½ teaspoons
Sodium Bromide - 3½ teaspoons
Sodium Bicarbonate (spa up, baking soda) - 5 teaspoons
Sodium Carbonate (soda ash) - 6 teaspoons
Sodium Bisulfate (spa down) - 4 teasthingys (HA! gotcha)

I usually add exact amounts like; about a half a cap, about a full cap, a little overflowing and then a little more... ;)

So...

If the GRANULAR Baqua Calcium increaser says add 6 1/2 ounces to raise the CH by 80 ppm on my 400 gal Vanguard, and the little plastic scoopie thing that came with my start up kit is graduated in ounces, do I add 6 1/2 of these ounces to the tub if this is what I need?

Now the LIQUID Shock that is added once a week says to add 4 ounces.  

The real question is do I use the same scoopie thing that is graduated in ounces for both the granular and the liquid?

Thanks

Tim

And I thought we are supposed to cut down on the sodium!

Ya gotta love the American system of measurements  ;D Some the liquid chemicals I have are calibrated on the side so you can see how much to dispence. The calibrating is in liquid ounces rather than weight ounces.

This would lead me to believe that dry chemicals are measured in weight ounces, and liquid chemicals in liquid ounces.

"This would lead me to believe that dry chemicals are measured in weight ounces, and liquid chemicals in liquid ounces. "

That gets back to the original question. When the reommedation is to add a Tbsq00n of something; what are we to interpret? A thingy of dry added to water? That is sort of what I am doing. But to be precise I was wondering if it meant that the chemical when dissolved into the form which is introduced into the tub. In this case I use a quart jar and eyeball, mine is calibrated of course, a few thingys into it and shake it up and pour into tub with jets on.

Been a long time since Chem 101. What does it mean something is added to buffer something? Language skills are elusive this morning?
