Help with Seachem Prime,

[Country joe]

Can anyone who uses prime, work out the tank dosing, I'm finding the instructions complicated, I want to dose a 70 litre Aquarium, sometimes a 50% and usually a 25% water changes, if anyone can give me roughly the doses, in mls or drops, it would really be appreciated.

For a 50% water change the dose is slightly under 1ml, for a 25% water change it would be half that.

5 mL / 200 liters = 0.875 mL / 35 liters

5 mL / 200 liters = 0.4375 mL / 17.5 liters

It's generally recommended to add Prime to the new water before adding it to the tank. But it's not always possible and the product works fast enough to be perfectly safe if added at the same time the water is.

Thanks for that I just looked up one ml is 20 drops and obviously 25% would be 10.
