exactly how much is 1 drop.. ?

[skeletor]

so I just did a little experiment with an old salifert syringe that I have been using to dose bak with, only to find out that with the tip off I get 20 drops per ml and with the tip on 60 drops. I've been dosing bak with the tip on and I feel like a total noob.

so, exactly how much is 1 drop of bak ? is it 1/20th of a 1 ml ?

excellent point. I always estimate 20 drops per ml. I use the large ZEObac and it has a dropper in it so i never realized it was that different. I guess I would suggest using it with the tip off

Thanks Madison,

how many drops per ml does one of the zeo droppers yeild ? has anyone tested to find out ? I don't have a spare and I don't wish to contaminate one of the ones I have.

I guess I've been underdosing bak by 1/3 and adding to much food I really wish I'd figured this out earlier, I feel like I just wasted 3 months of dosing.

Gary,

it sounds like Thomas really needs to add a dropper to the smaller bak bottle, or include one with it.

may have to rethink this because it may bring the price of the ZEObak bottle up. I know a lot of people may not like that. Every dollar saved helps them.

[Tom Berry]

It'd be worth a few more bucks to me. Every other product measured in drops, has a dropper bottle. It would make for consistent dosing across the board.

yeah I would really like to know the exact measurement of a drop. I have been doing the salifert drop method and have started getting algea build up on my glass. After reading this, I am wondering if my dosing is messed up.

Perhaps he could sell just the dropper on its own, so when people start they buy the dropper and bak byt from then on just the bak.

just an idea.

I'll see if I can get a dropper that would fit the small bottle. I'll let you guys know...
FWIW, the volume of a drop varies depending on the consistency of the liquid, the orifice of the dosing device, etc...my guess, and this is just a guess, I would say the ZEObak drop is about 1/10th of 1ml.

[skeletor]

I really think Thomas should answer this one, I'm just not satisfied with everyones best guess for an answer.

I will gladly purchase a bak dropper so I know that I'm putting the right amount in my tank, Pomme's idea of selling them seperatly seems like the right way to go.

thanks,
rich.

I agree with pomme, they should sell an accurate dropper/set of droppers and make it part of the kit. I would rather pay up initially than pay more for the additives for years to come. that way we are all dosing the same qty.

Give me a few weeks, guys....

while we wait for the official answer to the original question from our ZEOmaster Thomas I decided to do some more searching on the internet to see if I could come up with an answer myself.. anyway, this is what I found:

In either the US (Winchester) or the UK (Imperial) system of liquid measures, a drop is another name for a minim and there are 480 of these in a fluid ounce.

That's your first answer: if you have a volume in ounces, multiply by 480 to have the number of drops in it. However, since the US and UK ounces are slightly different, a drop is about 0.0616 cc in the US and 0.0592 cc in the UK.

The so-called metric drop is exactly 0.05 cc (20 metric drops to a cubic centimeter, or milliliter ).

Similar distinctions hold for teaspoons : A teaspoon is 1/6 of a fl oz (about 4.929 cc in the US and 4.7355 cc in the UK). So, there are exactly 80 drops to a teaspoon (in either the Imperial or the Winchester system). If you have a volume expressed in teaspoons, multiply by 80 to have the number of drops.

The metric teaspoon is slightly larger (5 cc) and the metric drop slightly smaller (0.05 cc) than the nonmetric counterparts, so there are exactly 100 metric drops in a metric teaspoon.

In a cubic centimeter or milliliter (cc, ml, or mL), there are exactly 20 metric drops and about 16 Winchester drops or 17 Imperial drops (more precise values being 16.23 and 16.89 respectively).

reading that just made my head spin even more.. I need another hit of zeobak now ---->

Rich, I'll take a hit too: Bob

If thats the case I've been underdosing as well, I've found that 0.2, or 1/5 of the salifert syringe with tip off is three drops.
