Ive just got a 100ml bottle to try, but unsure of the doses. Im only using it for a small 12lt shrimp tank im setting up so read that its two drops per gallon, but only the 50ml bottles dispense in drops. Can i use one of these eye droppers that i have?

You want about a ⅓ of a ml of prime for 12L of water at standard dose.
Couldn't tell you how big your drops are but you could count then into a 5ml spoon or the seachem lid which is usual 5ml, then divide 5ml by the number of drops it takes, that would at least give you the value of one drop.
Alternatively try and get an insulin syringe (1ml) and add a third of that.

One millilitre is 20 drops, so 12 litres is 6 drops.
(5ml x 20 drops / 200 litres x 12 litres)
(5ml x 20 drops / 200 litres x 12 litres)
I was thinking of just buying another bottle of the 50ml, and use the 100ml as a top up. I actually searched for how much is a drop of water, and found that a drop depends on what you are using to drop out of haha. It cant be far off the drops that come out of API test kits?
Im sure you cant overdose with this stuff unless you go crazy with it?

I’m about to have a similar problem - can you dilute it into a larger quantity of water, and then a use portions of that over a period of time?

No - I checked this with Seachem some time ago to see if I could dilute it for use with an auto doser, they said that Prime contains various stabilisers to ensure the working longevity of the solution. If you dilute those stabilisers they can’t guarantee that it will still continue to work as designed, which isn’t worth the risk with a product like this

FYI - the cap is 5 ml.

Why not
That's what the bottle says, but i've measured it before and it was like 6-6.5ml per capful

Lol, a good ploy from the marketing department to get people to buy more
1ml treats 10 gal or 40 L. Which is obviously too much for nano tanks etc. Unless maybe making bigger batches to store?
I know its concentrated, but im really surprised how little of this stuff you actually need to treat large volumes of water.
No good for nano tanks? Thats why i wanted to know the doses in drops. Which for my tank would be 6 drops or say 3 for a 50% water change.
Only fill it a third of the way 🤷♂️. Not going to matter too much if slightly out.
No i dont think it matters being a bit out as they state you can raise the doses when needed. The way my mind works is know the precise amount so i can see where i can break the rules with it. Im satisfied with the amount im using and the application of it, but it takes awhile to sink in lol.

If your tank is 12 liters then for a 50% wc you need 0.15ml. I just pour the prime into the lid as I use a large bottle and the syringe can't draw it out beyond a certain point. This kind of syringe can easy and accurately draw the exact amount you need Omnifi Solo 1ml Sealed Small Quality Leur Slip Syringes cheap 10- 400 Free P&P | eBay
If you want to use the dropper then it won't make much difference tbh.
Right got you. I wouldn't have been able to work out that amount exactly formula wise. Although its safe what im using ill most probably look into ordering those syringes.
